Comments: Mag 12 pump is very quiet and it gives me a lot of water movement. I had my old mag5 for about 6 years and that's y I went with another mag pump for my new 90 gallon reef. Only thing I didn't like us that I had to go buy the top piece that connects to the return line

Comments: This pump works flawlessly. It pushes a stubborn reactor that other "higher power" pumps fail to do. I love the NPT fittings as well, thank you. Props to Danner. Although, I wish there were some kind of pad or suction cup to insulate from vibration where a hard mount isn't the best option. Whatever... I'm buying another Danner mag soon.

Comments: This is a powerful pump. I got the 9.5, but the pump rusts at the screw holes on the pump cover and the screws rust as well. I took the pump out of service for this reason.

Comments: Pretty happy - its in a very small pond and produces a nice volume stream over my little waterfall. The frogs are ecstatic.

Comments: I am an experienced aqaurist bit I am not a good "plumber" or skilled for DIY projects. However, I changed out my RIO with the pump and the experience was quick and easy.

Comments: Its a good quiet pump. Was hoping for more flow but all in all its a great pump. Noise was very important and it is very quiet. I would recommend this pump to anyone. So far i would not use any other. I have it on a 90. gal. tank and works well

Comments: I use two of these to do a water exchange between a 7.0 cubic foot chest freezer and a larger reservoir that keep my minnows in. I can't even hear these things run but they're cycling some large amounts of water. I'm very pleased with my purchase.

Comments: very pleased with the pump.

Comments: Quiet, efficent, reliable as an anvil, and generates very little heat.

Comments: This pump has been running for about two months now. Everything is doing well. Easy installation and clear instructions. I am using this as a return line on my 50 gallon.
<br />
<br />Just a note to anyone considering these pumps: Take note of the section in the instruction manual on the proper size pipe for optimum flow. For instance, this pump has an outlet of .75

Comments: I have used Sicce pumps in the past. I was not satisfied with the noise that associated with them as I have two 90 gal tanks in the living room. The Mag Drive Supreme is much quieter than the Sicce, and much cheaper to buy. Overall I am very pleased with the Danner Mag-Drive Supreme pump.

Comments: Great pump, I have one as my main pump. Using another for my chiller main on a 1/3 HP chiller, Works great, I would buy again

Comments: This is my 3rd Mag # pump, I have 2 #5 and now a #7. Good for circulation. I have one doing my ATO, one circulating to my chiller and one for mixing water changes.

Comments: I am operating at approximately the 11 feet shutoff head and still getting about 1 gallon a minute for an auto topoff setup. Planning to raise the pump to get some margin and reduce pump stress a little.

Comments: Very quiet! I had to upgrade to mag 9.5 but this pump is an excellent utility pump. I would recommend it to anyone

Comments: Bought the Mag 3 because the Mag 5 was too strong. Was exactly what I was looking for. It has some noise, but definitely its usefulness outweighs that con.

Comments: The pump that came with my protein skimmer died. Customer Service recommended the Mag Pro 9.5 as a replacement pump on my Aqua C EV120. It has a small footprint, runs quiet and produces more output than the stock pump. It does run warm, but i have a decent chiller. Hopefully, it will hold up as the reviews tend to criticize the build quality of the impeller. I had to open the waste gate on my skimmer to handle the output. I hope to get more skimmate.

Comments: This has to be one of the best pump I've used

Comments: Very good!

Comments: Works well. A little noisy but no more that most other pumps. Mag pumps are some of the most reliable

Comments: Tried using pump for both return pump and feeding skimmer, works well for both jobs but.. increases water temp and lots of noise(drowns out all other pumps from systen). Good price and pumps a lot of water. Currently using for skimmer pump but will replace with another pump in the future and use the Mag 7 for water changes ect. Can't get over temp and noise.

Comments: I bought the Mag 5 and it works great so far. I use it as the return pump from my 29g sump into my 55g display tank.

Comments: Pump came fast and complete. Hooked up fast and easy and works great.Thanks!

Comments: great pump, pushes a lot of water, using it on a 90 gal ref tank. gave it 4 stars because it shows a pad to sit on in sump but it does not come with one. pump is rather quiet but would like to hear it with pad. i would buy again. mk

Comments: The mag 9.5 has been excellent so far. Very quiet, very powerful and fit where I needed it to. As far as reliability is supposed to be among the best so time will tell.

Comments: Used danner pumps in the past,will continue to use them.Very reliable, Great price. Easy to maintain. A great all around pump.

Comments: I have purchased Mag Drive pumps before and this one is excellent and quiet.

Comments: Mag Drive pumps are the Best. Been using them for over 8 years with no issues. little load and puts off a little heat but ill take it for the realiablity and pressure you get from these pumps

Comments: Great pump, have used them foir years. They last and last.

Comments: I have this mag 9.5 going up to a 50 gallon tank, 3' higher than sump, and I should of had a much larger drain than 1". This pump is about as loud as my zoo med 501 canister filter. I have three 1/2" ball valves restricting the flow at the tank, draining into a 20 gallon crabitat/sand bed draining into a 25 gallon sump. I would use a 2" drain if I was to use this pump on another tank. I used 1" pipe from the pump to the tank. 3/4"-1" adapter at the pump. freshwater setup.

Comments: I just replaced my old Mag 1800 with a new one after 13 years of 24hr/day use! I would say that I got my money's worth! The old one is still running - just not as strong as in its early life. The new pump gave a noticible increase in water flow. It is quiet and even smaller than the previous model. Shipping was quick. Would definitely recommend MagDrive to everyone. Well built. Strong. Easy to clean. Love it!

Comments: I purchased this pump to make a waterfall for my small fiberglass indoor pond. It does a great job!

Comments: Used danner pumps in the past,will continue to use them.Very reliable.

Comments: I use this for my sump return in my salt water tank. This is the third one I have purchased over the past 5 years. I think that ~2.5 years of continuous use is pretty good for any product, especially one submerged in salt water. I would recommend this pump, but have another on hand or be ready to order another WHEN it fails (everything fails at some point).

Comments: Love these pumps! They last a long time, they are totally sealed, and powerful. I just ordered two for my reef system can't wait to get them in action.

Comments: Typical of Mag pumps, they run great and last forever. I have Mag 12's on two of my skimmers and this Mag 7 is an upgrade for a mag 3 return pump on a smaller tank. I needed more head pressure and flow and this pump produced it. However it is a little noisy as it vibrates the return plumbing. A rubber pad on the bottom should eliminate this minor vibration.

Comments: I have a 180gal with dual drilled returns, and a 55gal oceanic sump drilled. I put 2 of these 950's on it with average 5' haed hight, and they screeeeeeam!!! had them going over 2 years with not one problem. The best! One recomendation to new users, if you have and of the mags, and your system is off for a while and the casing to the pump cools, you will notice some dripping. Do not worry, when they are running they warm up and stop dripping. Had it with my 500gph mags too.

Comments: I purchased the mag 5 for my 20g sump. I am using a CPR overflow box, 120g rated, for a 80g tank. This return pump is working great with little noise. I placed a ball valve on this pump to match the water flow from the overfow box. Would recommend to anyone

Comments: My Rio was getting old (rated at 695gph) and you can see a big difference with this pump, I used it on a 55g with 4' lift.
<br />Great quiet pump.

Comments: Started out my 72 gallon bow front with a 500 gph my buddy told me I needed more flow so I got this one.
<br />Kick butt pump got the water rolling will get another one for backup.Easy hook up and maint.

Comments: This is a fairly reliable pump. I run a mag 12 and have this one in case it dies. The important thing is to keep sand out, and clean at least every 3 months with vinager. I gave an extra star because if the pump dies within the 5 year warranty you can pay to ship it back and they will take care of you. I have sent 1 back so far no problems.

Comments: It

Comments: I stuck the pump in a bucket of rocks until my sump is ready. But my wife couldn't sleep due to the noise-from another room! Looked at it today and found that the impeller doesn't quite cover the shaft, allowing it about an 1/8" of wiggle room causing a nasty rattle. It does move a lot of water and have a small footprint, so two stars. Also runs pretty hot, if I run it, it'll be external.

Comments: This is an amaing pump.I use this as a circulation pump for my 600 gallon hot tub...and because its got a ground plug, is very safe. I use it with a GFI switch of course.Its hard to believe it runs on the power of a light bulb.Great product !!

Comments: I purchased this to run my HOB UV sterilizer. It's doing a great job. Powerful and quiet. This is the 3rd Mag-Drive Supreme I have purchased and it never dissapoints.

Comments: This pump seems strong and I believe performs to specification, but it is very loud. Probably fine for an outdoor water feature, but not for an aquarium unless you are not concerned about noise.

Comments: I've been running 2 Mag-18's for 5 years non-stop. I soak them in vinegar yearly, but they're never dirty. They're very quiet. The only way to improve it would be energy and heat efficiency. Then it would be 5 stars. I just bought a 3rd for backup because i'm in denial something can run for 5 yers and not break.

Comments: A very quiet pump with practically no vibration. Used it in a 20 Gal saltwater aquarium sump to recirculate water to a 45Gal tank.

Comments: I use various size Danner Mag-Drive pumps for circulation, to power my bio-reactor, etc. I continue to be very happy with them.

Comments: Bought this for use with my ATO. What can I say, the pump works, comes with a couple different adapters for hosing. Price was right for such a low (needed) amount of flow.

Comments: Pros:
<br />Pretty Quiet.
<br />Raw Power.
<br />
<br />Cons:
<br />Umm.... Nothing

Comments: this is a very solid pump. I got it for my 15 G sump that goes roughly 4 feet below my 40G fowlr. The outlet was 1/2" so i had to use a CPVC adapter to connect a 3/4" pipe. Either way, the flow is extremely strong. I read a lot of reviews about how loud it is. I disagree. It's true that the more you restict the flow the louder it gets but even then I do not think it's loud. Have been running it for about a week and a half now with no problems. Make sure you put a pall bearing in to change flow.

Comments: really strong, well designed pump, puts out a bunch of water. It was delivered quickly and worked immed., very please.

Comments: This is the 3rd Danner pump I've bought for different applications. I think for the money they can't be beat. I have an 1800 gph for my main return pump that has run constantly for 4 years without a problem. I just bought this pump for my chiller, and it works like a champ.

Comments: I rate this pump 5 stars:I have used various Danner Mag pumps since they became availabe for purchase years ago. I would rate this pump excellent in quality and durability with flawless operation. The last Danner pump I purchased has been in operation for the past 6 years without missing a beat(24/7). My new Danner 9.5 Mag pump will be placed in a 350 gallon fresh water pond (operating 24/7 as well). I strongly recommend Danner pumps to anyone who is considering a Mag pump purchase. Thank you Matt W. Columbus, Ohio USA

Comments: Using this to pump RO/DI water from the storage bin to the reef tank and from the wastewater bin to my grass. It works well and is easy to use.
<br />
<br />Only complaint is that it's easy for the outer cover to slip off and that can be a slight annoyance, as the inner pieces will pop out of place and need to be reseated. This only takes 30 seconds, so it's not the end of the world.
<br />
<br />It's pretty quiet and vibrations are sensed rather than truly heard. I haven't noticed any significant heat being generated either.
<br />
<br />I'm a reef noob but I've kept Malawi cichlids for close to 10 years. So I'm not a pump expert by any means...

Comments: A little disappointed ! The pump states,at a four foot head it will pump 800 gph. Even though i branched it off to a 1/10 chiller with 3/4 in tubing, the flow rate was reduced to 180 gph. I don't think they have there specs right,the chiller wouldn't have reduced it that much.

Comments: I just upgraded my return pump in my reef with the mag 18 and it runs smoothly and has zero vibration. The reason I decided to go with a mag pump is that I've used a mag 24 in my pond for 7 years, running 24/7/365 and it's never failed.
<br />
<br />Great bang for the buck.

Comments: when I just got this pump, it seemed to run fine except for significant vibrations and noise. I had several larger MagDrive5 over the years and they were never quiet so I thought this was normal. Unfortunately after just 1 week of use the pump has failed completely, impeller broke off from the rotor magnet. Build quality seems to be rather poor.

Comments: I bought this for my return pump, couldn't make it a full day with the noise. Works great if sound isn't an issue. I am now using it for a mixer pump.

Comments: REPLACED THE ONE ON MY REACTOR, WORKS GREAT!

Comments: Nice little pump

Comments: Bought this for my husband. We had a 1200 that the impeller had to be replaced on. While it was being repaired we ordered this and intend to use the 1200 as a backup. Wow!! The only problem is that it is so powerful I had to install a T returning to refugium. Didn't want to valve it down and strain the pump. It's quiter than the 1200. We have a 90 gallon tank and we could probably keep our wavemaker off and just run the main pump.

Comments: I purchased the mag drive 9.5 to run the aquac ev-180 and I have no complaints what so ever. I have only had it for a week but so far it seem to be very powerful and quite and its pretty compact for a pressure rated pump

Comments: loud, huge power usage, doesn't start up right, hard to clean, Danner has bad customer support!
<br />
<br />only good thing about this pump is it can push water once you get it started which might take a few smacks
<br />
<br />I broke the center shaft cleaning this pump called Danner they will only sell the complete impeller assembly not the fragile center shaft instead of buying a new impeller assembly for $16 i will put that towards a better pump

Comments: I was using RIO HF5 with CPR 90 overflow, but after few months of use, it seemed like it was losing power. So I switched to magdrive. So far so good. We'll see how it is in few months.
<br />

Comments: I'd had a Mag5 plumbed-dry on my CO2 unit for my planted tank for 6-years. It ran dependably and silently for 6-years until its impellar went. I ordered a new one and while waiting for it, I neglected to unplug the Mag5 because I had a lot of other stuff on my mind...and...it, of course, seized. So, I ordered a Mag3 (the Mag5 was a little over power for this application so my error, at least, gave me an opportunity to fine-tune) and I have it working now for over a week. Also, I believe the Mag5 and Mag3 use the same impellar. It's hooked up in the exact same way that the Mag5 had been and it's working dependably and silently, as I had expected. I know some people encounter vibration or noise from the Mag pumps but I've used them extensively (I have two in the sump of my reef-tank, also for 6years) and I find them to be great pumps every time. They never make a peep and they stop and start on timers, for feeding, etc. I think it's a matter of being very careful to get all the air out of the pump before it's started up, whether plumbed dry or in a sump. If that's done correctly, I think there's no way that anyone'd experience any noise at all.

Comments: THE PUMP IS SUPER, WE USE IT EVERY DAY.

Comments: Been using the mag 5 on my return and protein skimmer since I started my reef tank. They're great and never have had any issues. One of the best pumps out there and very quiet with low power consumption.

Comments: we've been running this pump in the sump for our 240g. saltwater aquarium, for 3 yrs. now & it has run like a charm so far... we've had power outages, surges & it always kicks right back on.

Comments: Pump quit in 4 weeks. Do not buy

Comments: I used three pumps and this one was unique and easy to use. The sponge for this pump is out side which make it easy to clean and without turn off the pump. I recommend this for using carbon in TLF.

Comments: Well Ive had this pump running for a couple of weeks now and it works well but it tends to make bubbles. Ive checked every possible other suspect for the bubbles but have found it to be the pump. This pump is also a bit noisy compared to others which is no bug deal but worth mentioning for those who want quiet. The thing that kind of bugged me the most about this pump is that it does NOT come with any adapters or accesories. All the other pumps ive purchased come with these things. Im not that impressed with this pump.

Comments: Really not much to say about this pump except to say it works very well. It is a external or submersible so its versatile application is nice.
<br />
<br />Mine is hard piped into the system with threaded PVC. You can set it up with screw in hose tips and run flex hose if needed.
<br />
<br />As I said versitle application. Good unit.

Comments: The pump works great but there was not pad in the box for vibrations

Comments: I purchased this for use with a Precision Marine Bullet 1 skimmer. Works very well.
<br />Mag Drive pumps are very quiet.

Comments: I have a 75 gallon with sump and I use this as my return pump. Works good... I should have went a tad stronger but this works fine. Been on for a year straight..

Comments: The quality of the pump is top notch. I had to go to a plumbing store to get the parts I needed as Lowes didn't carry much of a pvc selection. It was easy to plump straight from the pump to the chiller and back to my return/bulkhead. I have about 7-8 feet from pump head to the tank return and the flow is not as powerful as I expected. I would go with the next pump size up (as long as the dimensions are the same), as it fit nicely in the rear part of my 60G uniquarium. It did not come with rubber feet so I have some vibration noise which I do not like,but I may just put a thin piece of filter foam on the bottom to remedy that issue. The pump head can be moved 90 degrees to make the pump profile a little smaller if needed. Overall I like the product and would buy again, but one size bigger due to the length of hose I have with my setup.

Comments: Everything got here quickly but my pump looks like it was dropped and had marks and scratches on it. But it works

Comments: Water pump works perfect!!

Comments: I am using this pump as recommended as one of two pumps that come with the AquaC EV 120 protien skimmer....I have been using the Rio 2100 which mysteriously is now too strong and fills the chamber with water.....Upon setting up the Mag drive, which is a very strong pump...too strong..the ceramic shaft snapped in two after about 10 min. into use....I was able to bore out the rubber heads that hold the shaft to allow rotation and glue the shaft inside the magnectic housing and the pump is working until I get a new shaft...seems a metal shaft would make more sense....The pump is quiet and strong and seems to do the job....It does not produce as much foam as the 2100, but at least it is much more adjustable for use with this protien skimmer. The really nice thing is that it is much smaller than the 2100 and fits in tight spots much better....

Comments: Well, On my 180G reef I use a mag 12 and my mother wanted a new pump for her pond. She was looking at a $79 home depot pump which while powerful, wasn't durable. The Mag 7 puts out the same if not more water for the same price, and is sure to last me for many years to come.

Comments: A good solid pump.
<br />+ seems to be good flow, I have mine dialed back to about 50% on a 20L with a 15g sump, and a 4ft head.
<br />-no suction cups included.
<br />-just a slight hum, but not enough to make me switch brands.

Comments: I had put off ordering this pump because of the price, but I have changed my return pump three times for various reasons...mostly the noise or the strength of the pump...but I installed this Mag 18 for my 150 gallon and my water is sparkling..it's super quiet and it really moves water! Great pump...I only wish I had made this investment sooner. Thanks!

Comments: look like its built like a tank but don not install this pump outside the pump. after 3 days of use i inspected the pump i i saw salt leaks from the cover attached by screws. looks the the pump could use a better O ring to prevent this. from the the beginning, this pump was not all that great. when i started it, it has such a rough start i thought the thing blew up. i was extremely disappointed with the results of this pump. i sent it back

Comments: I like these pumps but it seems like after a few years the gasket will start to leak. I've had the same thing happen to 2 pumps already. This is my third pump. If you get the pump, and it is in an area that you can't have any leaks, set it in something so it will leak in the pan. I was able to fit a cat litter pan in the area where the pump sits, so it literally sits in the cat litter pan. When I notice standing water in the cat pan, it's time to get another pump.

Comments: I have used Danner Mag-Drive pumps for over 10 years with EXCELLENT result! I highly recommend these durable and reliable pumps!

Comments: Great pump for the price. Easy to maintain. A great all around pump. Had my last one for five years with no complaints.

Comments: I have owned several of these pumps, a Mag 7 and Mag 5. Both do exactly what they are advertised to do. Never a problem and that's what you want in a pump.

Comments: Very easy installation... and immediately you could see all the junk leaving my tank into the overflow... Only thing now is, keeping an eye on my sump socks and protein skimmer.

Comments: I am using this as my auto topoff pump. I have to pump about 12ft up and another 10ft to the sump. Pump works great. Its quiet. I cant even hear when its working.

Comments: Great pump...as always.

Comments: Good flow and well bilt just wish they put some sort of rubber feat or suction cup for the base. If it had a better base it would have gotten 5 stars. Good buy

Comments: This is number 4 and 5 that I've ordered. GREAT PUMP!!!

Comments: It is working great..Thanks for sending it so fast.

Comments: quiet and lots of water what else do you need great pump

Comments: Electrical issues from the power company fried my last pair of pumps. Ordered 2 of these for my 180 gallon aquarium. I've had them running for about a week now. They are quiet and I have no problem pumping from the bottom filtration tank up to the discharge point (about 6' of head pressure). They work well.

Comments: Danner's Mag-Drive pumps have a reputation for being extremely reliable, and this is what made me decide to order my own. After seeing these pumps used in friends tanks for years without need for maintenance, and no issues arising with them, I can only assume they are quality products. My concern with the pump adding heat when ran submersed has not been realized, my tank is actually staying cooler even with this pump running.

Comments: I purchsed the Mag-drive 5 for my sump/fuge. Pump works great in my application and the noise is tolerable. It is not the quietest out there but fo rthe price you cant go wrong.

Comments: This review is for the Mag drive Seven(700gph). All that needs to be said is WOW. This pump is great, I am building a new sump and this thing can pump. My head height from sump to top is 5.5 feet, but still this can put out some water.... My only concern is the vibration from the impeller. You might think its motor noise but rest asssured its just impeller vibration that you can easily fix with some isolation feet on bottom of the motor housing....great pump plan to by another...
