Comments: These are what you need. I wouldn't use anything else

Comments: Great product, just a little pricey. Worth it to quit worrying about having the maxijet powerhead falling off the glass and spewing sand everywhere.

Comments: Great Product
<br />Works as stated.

Comments: Lets you move your pumps anywhere you want.

Comments: Simply stated, it works and it works well. I had been having trouble with my MaxiJet 1200 suction cups holding. Now I can place the unit in the best location for my reef's water flow and it stays put.

Comments: I have a 150gallon tall. I got the extra size upgrade thinking that it would be better, but the little rubber feet on the magnet take the versitility out of it. Mine came off both inside the tank and outside the tank, I guess it wasn't supposed to be used to position the powerhead. Also the adapter to the powerhead bracket isn't that tightso if you try to rotate it 90 degrees your powerhead might slip off. I probably will not buy this product for my other tanks. Great concept, poor implementation.

Comments: These are the magnets that should have come with the maxijet 1200 a little pricy but well worth it no more suction cups :-)

Comments: We have a 55 gallon tank. The flow is terrific with both impellers but very very noisy and a lot of vibration that is not able to be adjusted no matter how you try. The magnets hold very well.

Comments: These magnets are very strong and work well on a 3/4" acrylic wall.

Comments: I think people are so happy to rid themselves of suction cups that they have ignored all of the drawbacks. First, for what you get, it is terribly overpriced. Second, the unit is difficult to adjust, so unless you have a lot of room to work with, forget buying it. Third, the magnets are strong (and somewhat dangerous, unless you don't mind getting pinched), but forget about using this size model on a rimless reef tank with thick glass, It won't hold. Last, if you don't have one of 4 or 5 recommended powerheads, don't bother, it won't fit.
<br />
<br />If you meet all those requirements and most people will, then consider buying this.

Comments: Wow these are wonderful. Watch your fingers and your glass tank as these are very strong. Really good product. Now I'm just wondering if they are algee free or if that's just the name if the company. But yes get them worth every Pennie.

Comments: This is a very strong magnet. Works perfect.

Comments: Works flawlessly! Perfect hold, very strong.

Comments: These are incredibly strong magnets. I am using them on a 90 gallon aquarium and they hold a Maxi1200 with the SureFlo upgrade without a problem. Infact watchout for the pinch factor.I am convienced that these could remove a finger if given the chance. The only reason I gave them a 4 star was because of high cost.

Comments: it works well and is compatible with many powerheads

Comments: This is the second pump bracket that I purchased. Bought the first one to check it out before buying another one. I had been frustrated with the suction cup brackets and was pleased with this magnetic bracket. Haven't had to do anything to it, it's great to look at the tank and NOT see a pump dangling in the water because the bracket failed again. Worth every penny I paid for it.

Comments: With the 1600 mod, it made the Maxijet 1200 shake. The suction cups are no good, it got loose instantly and made lots of noise when the powerheads were turned on. Made a big sandstorm when the powerhead fell to the bottom, nothing was happy. Got the SureGrip 100, and wow. The rubber ends silence any noise that the powerhead is making due to shaking. I have a hard time taking it off from the side glass. Careful as these are strong, pinched my fingers and it hurt. My only complaint is, I wish these were cheaper.

Comments: Easy to set up on the maxi jet power heads. Good strength on the mags. Worth the money to ensure your power heads stay in place.

Comments: This is the perfect upgrade for those who use the older Tunze Stream powerhead. You can place the powerhead exactly where you want it, regardless of the type of light fixture and /or hood that you have.
<br /> The magnets are super strong and the rubber "feet" are a nice touch that will prevent scratching of the tank walls.

Comments: Holds my modded maxijet PH in place very well. Only gripe I have with it is that it really does "grip" the glass and its not possible to position it exactly where you want by moving the outside magnet only. I was hoping I could keep my hands dry :). But it holds very well so far after a weeks worth of use.

Comments: WOW!! Finally someone came out with something to modify the old "suck"-ion cup" style attachment!! Very sturdy, stays in place...even in an earthquake!

Comments: Much better than suction cups...well worth the money.

Comments: What a terrific product. Super strong and would hold much more than a power head to the glass.
<br />I love that I can make different configurations for the power head with the enclosed attachments also.
<br />A really great product for the money.
<br />Thanks Marinedepot for a great and much needed product.

Comments: very strong magnet, works good but watch your fingers....ouch

Comments: Wow!!No more "sandstorms" in our tank! Almost did not buy these due to the price - sure seems high for a magnet, doesn't it?? However, we are glad we did -they are so worth it for the peace of mind! Ordered 3 more-splitting the order w/a friend who wanted some after hearing how well they work w/the maxxi-jet 1200's.Our glass is 1/2" thick and the 50's work great - they will NOT slip unless you purposely pull them apart. In fact, the magnets are so strong that you'll have to be careful not to get them close together in the process of installing - I have a blister on my finger to prove their strength. No more keeping the powerheads to a minimum just to minimize the risk of failed suction cups. Now we can use all of our powerheads and not keep throwing money at suction cups that only work temporarily at best! Fabulous product!

Comments: These are amazing! powerheads remain where you want them.

Comments: I'd had nothing but problems with my Maxi-900 suction cups no matter how clean my glass or the cups themselves were. The sure grip solved the problem. My powerhead is now going nowhere, these magnets are ridiculously strong!

Comments: This product keeps those powerheads attached. No more worries about the suction cups letting loose. Glad we purchased several.

Comments: I've had trouble with the magnetic powerhead holders that come stock with some powerheads not being strong enough to hold through my tank's 1/2" thick acryllic. This magnet attached my modded MJ1200 quickly and securely.
<br />

Comments: I use these with my 1200 Maxi-jet mods. Extremely strong. I think I could have got away with the smaller ones. Don't worry to much about kids being able to slide them, it won't happen. I tried the DIY version of magnetic holders, in the end it was not worth it, just buy these you won't regret it.

Comments: I bought one of these and it is awesome, my power head kept falling off and I replaced the Suction cups multiple times, with this new Sure Grip it holds tight.

Comments: I applied the magnetic powerhead holders to my maxijet 1200 powerheads. The powerheads have not moved an inch - it's great. For the first time my water flow is going directly where I want it to.

Comments: Brilliant

Comments: The Magnetic Powerhead Holder is unbelievable! DEFINITELY holds the Powerhead in place. I need to order another one!

Comments: I highly recommend this product as it not only works great. it will prevent a major problem like I experienced below: Anyone should use this product if you want the powerheads to stay where you put them! Read the horror story below...
<br />
<br />Previous suction mount failure - I mounted two Maxi-Jet 1200 with the Sure Flow Upgrades in my reef tank using the included suction cup mounts. Everything was fine until I came home one day and found that one of the suction mounts had come loose allowing the power head to point straight down. The result - it blew all of the sand base out from under the rocks, causing a complete colapse of my live rock structure.
<br />
<br />I strongly recommend using these Sure Grip 50's Magnetic Mounts to prevent this from happening to you!

Comments: After several years of being a Saltwater enthusiast dealing with internal pumps held by suction cups that after time quit holding I came across the sure grip. What a great idea so I bought it and tryed it.WOW what a great product. The magnets are very strong and even have rubber feet so you don't scratch your tank. These are the best thing ever and they stay put! Great product. I highly recommend this to any one in the fish hobby!

Comments: Algae Free Sure Grip 50 Magnetic Powerhead Holder are the best product I have ever added to my reef. They come with an adapter for every brand of unit. The small rubber feet on the magnets keep the powerheads from sliding on the tank glass. No sand storms, No shutting down the heads for cleaning, units slip on easily so changing out a clogged unit is a quick change with a spare. These holders are so good they should be required by the powerhead manufacture - It makes their unit better!

Comments: Product had the strongest magnet I have ever used,was quite compact and had the correct mount for my Seio powerheads.Was a little pricey but I had had it with suction cups failingon original mounts. good product.

Comments: A great product.Easy to use.I use three of them on my maxi jet powerheads in my one hundred gallon reef tank.

Comments: Aside from the price, this product is worth getting. I purchased 3 magnet holders for some maxi-jet pumps. These puppies are in the same position as I left them months ago. The sucker cups I had would always fail and the pumps would create sand storms. Although they are expensive, It's definitely worth it.

Comments: No more worries that your powerhead will come loose, potentially harming your investment in livestock. This item is works beautifully. Your powerheads will stay put until YOU want to move them. Have you ever had your powerhead come loose and damage that new expensive coral that you bought or blow sand everywhere? Stays put, but moves easily for cleaning. Brilliant.

Comments: Works fantastic! I used mine with my modded mj1200 and it works great. I had to glue the pivoting piece to the in-tank magnet. I used loctite gel and has no issues. Holding stong without any issues! Fantastic product.

Comments: Very strong, easy to assemble with maxijet powerheads. Highly recommended.

Comments: This is great, it allows me to put my powerhead anywhere I want to. Magnet is super strong. I would recommend

Comments: I found this magnetic powerhead holder to be a neat item. It went together easy and now I don't have to worry about those suction cups letting go and my powerhead falling off.I'm glad I found this!!!
<br />

Comments: works pretty well. The picture shown on website is kind of bad. It 'looks' as if the powerhead is leaning slightly, or that it is a bit loose to the magnet. Not so. The magnets are strong, the connection is tight, and it aims the powerhead straight out. If the suction cups are pissing you off, just fork out the cash and get these. Its worth it to me.

Comments: Used this on 12mm glass and it works fine (much better than the suction caps), but I've had some difficulty when I've tried to slide the magnet across - I'd probably recommend the stronger model magnet for 12mm glass.

Comments: Limitless application , they are very strong, will not harm glass. I have four power heads and i have a set on each one. Iam able to configure my power heads for maximum flow. A geat way to make your reef system come alive.

Comments: Say "GOOD-BYE" to suction cups, these magnets are just fantastic. I am using them on 4 modified Maxi-jet 1200's in my 180 gallon Reef Tank and after 2 months--NO SLIPPING. This is the ONLY way to go.

Comments: This product is adequate. FYI, I placed my powerhead in a hard-to-get-to spot, so I learned you really can't move it's position by moving the outside magnet. It also helped not to have the powerhead mounted yet while you choose the location because it is awkward and my maxi jet powerhead slips off the mount easily (it holds fine once in place, I'm just talking about when I'm positioning the pump).
<br />
<br />The price is a little steep for a magnet, but it is the only alternative to suction cups. I'm glad to get rid of the suction cups mounting method.

Comments: great product, will never use suction cups again.

Comments: but seems high priced perhaps its just me :)

Comments: Excellent product. Easy to use. No more suction cup failure.

Comments: This item is a must have with the Maxi-Jet upgrade kit.I thought it was a bit pricey, perhaps because of all the adapters included for all the different powerheads out there? Still, cost aside, it is a great idea and it beats the cheap plastic powerhead holders that always break.

Comments: Maintains a great current without the slipping and sliding of suction cups.

Comments: Forget about suction cups. This magnets are the real deal, they hold on tight. I like the small rubber feet they come with, nice touch, so one does not damage his/her aquarium. I have two sets holding my powerheads and could not be happier. They are an excellent choice when using the upgrade kit for Maxi Jets.

Comments: Great product, very easy to install. The power head has not moved at all and it looks so much better than the hang on clip that came with it.

Comments: Have always had problems with the Maxijet powerheads falling off my aquarium because of the suction cups. Brought two of these and now I can place the powerheads just about anywhere in my aquarium.

Comments: Works Great

Comments: Great quality, you don't have to worry about suction cups falling loose, and having sand storms in your aquarium. Plus they are not that big.

Comments: Get the big one. I got the 50, no problems, it just feels like it could be stronger. The Maxi mod is awesome though!

Comments: I have four Sure Grip 100's in my 150 Oceanic.I am using them with maxi-jet powerheads with upgrade kit that puts out over 1600 gph each with wavemaker.Hasn't moved a bit!Easy to set up and you can place powerheads anywhere now.Great product.Won't ever use brackets or suction cups again.These are very strong magnets so do not get your fingers etc. in between them!

Comments: excellent, easy to install

Comments: One of the best products in aquariums....

Comments: Great product!!
<br />No more powerheads falling off.

Comments: You will need one per powerhead. Good product, but a little costly since you have to buy one for each powerhead and you have three extra brackets.

Comments: I purchased this product because I got tired of buying new suction cups for my multiple Maxijet powerheads. The magnets work excellently. Little rubber pads protect the glass. I use mine in combination with the Maxijet modification kits sold elsewhere on this site. My only qualm is the cost. Unfortunately, there is no real competition.
<br />Still, if you too are tired of suction cups failing and blowing your sand all over the tank. This is the only way to go.

Comments: A wonderful device! It is so easy to manipulate and you never have to worry about suction cups! Excellent!

Comments: I have had mine for about 6 months now, and I love them. I love that I never have to fix a suction cup again .

Comments: Great product, I guess it won

Comments: Excellent product,very strong magnet,don't get fingers between magnet.

Comments: After seeing the size and quality of the Sure Grip 100's in comparison to its Tunze counterpart it was a no brainer which one's I would purchase. I have friends that have each of the afore mentioned. The Tunze are just an eyesore on the tank. Big bulky and obtrusive, at least in my eyes. The Sure Grip 100's are compact, yet extremely strong. Not to mention they are much cheaper than its previously mentioned counter-part. They earn a solid A+ in all categories for me: Price, construction, performance, and aesthetics. Whenever I need magnetic holders I will without a doubt purchase these again.

Comments: It works great buy why does it cost so much?

Comments: This product works wonderfully. It's simple to use (it's a magnet) and keeps
<br />my filter exactly where I want it. Not only does my filter stay put, but I know longer have to dig my hand in the tank to remove or reposition it. I highly recommend this product..

Comments: SIMPLY THE BEST PRODUCT I HAVE EVER USED TO ATTACH POWER HEADS
<br />NO MORE MOVEMENT, HARD SUCTION CUPS OR FALLING POWERHEADS. I HAVE BOUGHT 4 AND PLAN ON BUYING 4 MORE. WORKS GREAT WITH MY WAVEMAKER.
