Comments: Pros:This skimmer rocks. It was easy to set up right out of the box. It is easy to adjust water level with the adjustable pipe. It can be modified but I have chosen to run it stock for awhile to see how well it does. It started producing skim within the first day. Really no break in time. I have a 150 gal reef with a 40 gal sump. the unit sits in the sump well even with its large footprint. Price is good for this skimmer. It does the job it was designed to do
<br />
<br />Cons: has some noise from airline some my not like. It doesnt come with anything to cover the inlet so small inverts could get stuck (modification to raise off bottom)should be considered.
<br />
<br />I would say that this is worth the money. price 250-375

Comments: simple setup small foot print in sump very quiet and produced skimmate in less than 24hours I would buy another any day

Comments: Great product. My 50 gallon tank does not have a lot of room in the sump. This small footprint did the trick. The pump is buried under the unit. Nice design. It works perfectly. For the price this was a great value.

Comments: This is our second ASM Skimmer. We had a smaller model which was too small for our upsized tank that we had previously used on a smaller tank. We did not hesitate to buy a G4 Plus. It was easy to adjust, and we were skimming in minutes. Just follow the instructions, which will have you start the pipe higher than you might think. As the unit runs in, the pipe will end up being a bit lower. I will also note that at one point we thought our smaller ASM had a problem, it leaked skimate from the lid, no matter how dry we made it. Turns out it was just too small for the additional bio load we gave it, and the bubbles did not break down in the catch chamber: the moral of the story?, don't undersize your skimmer. . .

Comments: Works great but for novices they need to know that it takes a few days to actually start skimming junk from the tank. Also there are no instructions at all which is ridiculous. The bad part: the pump is terribly loud.

Comments: Really works. 7 1/2" water from bottom and you can't go wrong.

Comments: At Feather River College we utilize the ASM G4+ for our 240 reef display. Its construction is solid, simple and provides great value. In these tough economic times getting the best bang for the buck is what it is all about. This skimmer quickly set to work on removing built up organics. It also began removing small particulates that were flushed out of the refugium that clouded the tank. There is no need to spend money for a name spend it on something that gets the job done.

Comments: This skimmer is not perfect, but is the best for the money; I use the ASM G-3 for my 210 gal. tank and it start pulling skimate on the first day; it is still doing the job after three years on original parts (I got a spare impeller just in case).Pro.: best price for the money, reasonable foot print, Sedra 5000 pump work very well and produce lots of micro bubbles.Con.: the instruction is terrible, does not tell you the operating water level for the skimmer (I sat my at 10

Comments: I love this skimmer! I have had zero problems with it. This is what I have on my own personal tank and several of my service accounts and it works great. I have never had a single issue with these skimmers after dealing with over 15 of them. For the money I don't think you could get a better skimmer.

Comments: I have used an ASM Skimmer before and liked it quite a bit. I thought overall it is a good value and it does a good job of skimming.

Comments: Very easy to use. Plug and play. Most capacity for the money.

Comments: Works great. Instructions were extremly vague, but Marine Depot was very helpful when we called for help. The "start up" level (you lift the tube up/down to adjust)was about 2 inches lower than shows on the vague instructions.

Comments: This isnt the best out there but it actually is a nice skimmer. I used it a couple of years ago and found that it was simple to operate and easy to remove the collection cup. It did a good job at removing waste.

Comments: The ASM G2 is a great protein skimmer. Operation couldn't be any easier, just plug it in and set the overflow tube to the right height. The bubble production is really amazing. It blows away my previous protein skimmer, a Red Sea Berlin. The only down side is the rubber grommet that connects the main chamber with the pump leaked microbubbles profusely when itially assembled. I superglued the grommet into place and eliminated bubble leakage entirely. I'm very satisfied with this product and I have recommended it to friends.

Comments: Decent construction. Easy to remove the collection cup.
<br />
<br />
<br />Lacks any directions or guidance. It would be helpful to know things, i.e. Proper water level in the sump, what height should the adjustment tube be set.

Comments: So I ignored some reviews because of this skimmer being an ASM......
<br />
<br />So two pumps at $50 a piece failed and the male portion where the collection cup connects to cracking and this is just 6 months in. Tack on the extra $200 I just spent on replacing this garbage........
<br />
<br />Sad to say but ASM is behind the game with this skimmer. Alot better options out there for close to the same price.

Comments: I have had this skimmer running on a 125 gallon reef/fish tank (new setup, tank not fully stocked yet) for about a month and it has been working great. It produces a great amount of micro bubbles and it pulls out a lot of junk from the water. The water level adjustment tube is sturdy and holds its position. It is far better then my old hang-on-tank protein skimmer I had on my 55 gallon tank. Only thing I don't like is a small amount of micro bubbles escape into my sump which then get pumped back into my tank. The foam around the water exit doesn't seam to catch many bubbles, it is to course. But that could be solved with a little tweaking to the sump. I would buy another one if I ever need it.

Comments: Love this skimmer. Has done what evne my Tunze couldnt do. The only thing I dont like is that my hands are small and I struggle to get the collection cup off.

Comments: I think the skimmer itself is fine, it works well (not all that bubbly in my opinion). However the G300 pump that it came with is extremely problematic. I had the starting one, it stopped running forward after about a month. We accidentally broke the ceramic shaft trying to clean it. So I ordered a whole new pump to have extra parts. I hooked that new pump up and it worked well for about 2 weeks, at which point it refuses to run forward again. With some position shifting and creative blowing into the hose you can sometimes get it going again, but all of these things are nearly impossible once it's in place in the stand since the pump sits under the skimmer.

Comments: The skimmer pulls decent skimmate, fits well in a small space and is very cheap, that being said, the needle wheel on mine has broken TWICE now. The actual wheel spins of center and locks up in the pump. They have the replacement needlewheels in stock, but after paying the shipping and waiting the week to ship it I would have been better off going with another brand.

Comments: Excellent skimmer hands down! Great price and easy to modify. Easily out performs the two smaller, but good skimmers that I had been running in my sump.

Comments: This skimmer is so simple, yet effective. Because it is so simple you are getting the largest skimmer for the price. It is very easy to adjust, just by changing the discharge tube height.
<br />
<br />It also comes apart in easy pieces to allow cleaning of the skimmer body and other parts. Not like some of the other 3pass models where you can't get to all of the inside surfaces of the skimmer body.
<br />
<br />Some people complained that it doesn't come with a manual, but my skimmer came fully assembled, so a manual wasn't necessary; There weren't a bunch of parts to mess around with.
<br />
<br />The only thing I would like is a foam block or other filter for the intake of the skimmer. Unless you have a super clean sump, you'll want to get a filter for the pump intake.
<br />
<br />Started pulling organics within 3 days.

Comments: The skimmer worked incredibly...for one month before the first pump failed. The replacement pump lasted one week. It's a shame ASM couldnt contract with a better pump company because the skimmer worked fantastically but the pumps are absolute junk.

Comments: Construction is great, size is perfect, but the pump used on the Mini-G is terrible. It's loud and I had to replace one after only a month. I would not recommend to anyone due to the initial price of the skimmer and latter price of replacement pump.

Comments: This is an excellent skimmer. Needle wheel pump makes an insane amount of bubbles and started skimming almost immediatly. Unfortunately, the pump is extremely loud. I'm on the fence with this one. Great price and works well vs. obnoxious.

Comments: THIS SKIMMER IS A PIECE OF JUNK DONT WASTE YOUR MONEY I HAVE CHANGED 3 PUMPS ALL NEW AND THEY ALL MAKE SO MUCH NOISE WE CANT EVEN GET TO SLEEP AND THE TANK IS DOWNSTAIRS.THE PUMP STOPS AND WILL NOT RUN HAVE TO TAKE IT OUT OF SUMP TAKE APART AND STILL WONT WORK.ITS THE WORST SKIMMER I HAVE CAME ACROSS.DONT WASTE YOU MONEY!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Comments: So far the G-2 seems to be working solid and is producing, about 1/5th a cup a day, i have a ton of live-rock in my 90 gal tank, approximately 10 Corals ( mostly soft ), and 7 fish.I was running a SEA-CLONE that wasn't working as good as it has in the past, but that would produce a thick blackish syrupy mix in the cup, just wasn't doing much lately. So comparing the ASM to the SEA-CLONE may not be a good measurement of a comparable Protein Skimmer. I haven't made any adjustments to the skimmer but I am hoping to get a darker more concentrated fluid in the cup.

Comments: This skimmer started to remove product right away.
<br />very easy to setup no real instructions.Thr 3500 pump made lots of noise and vibration at first but I believe this is just first time start up prime mode,the noise was
<br />gone after 24 hours.This product would be purchased by myself again for future aquariums.

Comments: I put one of these in the sump of my 120G sps reef. powerful pump. NO FUSS DESIGN!!! I cant emphasize the no fuss enough. Set the drain pipe height and forget about the endless tinkering and adjusting crap that a lot of skimmers have. Mine took about a week to get a slime coat and start pulling out the stank.

Comments: You can't beat the simple but efficient design and sturdy construction of this skimmer. Fit and finish on this skimmer is excellent and the riser tube design to adjust the water level is good although a little hard to adjust while the skimmer is running. The documentation that comes with the unit could be better. Overall performance is medium to high.

Comments: Great skimmer for the price! I have it connected to my 260G and 75G sump and it has pulled out almost a complete collection cup of gunk in 2 weeks! Other than it being a bit loud, I have no complaints!

Comments: The skimmer I recieved did not come with a manual. It only had one piece of paper with a crummy pic and and a few words. Sure wish it came with instructions on how to assemble, how to maintain, and how to opperate.

Comments: Very pleased at the price/performance of this skimmer. Extremely easy to set up and adjust - I adjusted the standpipe over a couple of days to get the skimmate where I wanted it (fairly dry), and haven't had to touch it since. Big change from my old skimmer, which required constant adjustment.

Comments: performs great after changing pump. returned first skimmer,it would stop and run, second skimmer did the same thing,checked the pump and it would stop after getting hot. called the company found they were having trouble with the pumps and they would exchange the pump.

Comments: I set it up in my sump to replace a different skimmer i had. The G-2 is working great and skimming very good so far. Lots of foam and skimmate. The acrylic body is thinner though than my previous skimmer, but this g-2 is a little smaller which is what I preferred.

Comments: when fist set it up in my sump i got a lot of air being diffussed thru the outlet tube, which really disturbed my
<br />euphyllia,but after playing with my sump level and letting it run a couple of days it settled down and after the fifth day it started skimming,and is now working great.very good product with economical price.

Comments: This skimmer rocks! Checkout the skimmer cup after 3 days here: http://www.everythingsalty.com/gallery/files/1/IMG_0646.jpg
<br />That's a lot of dark dark skimmate.
<br />If you get this skimmer you wont be disappointed. The motor is quiet also.
<br />I run mine on a 120G mixed reef.

Comments: I've barely had this skimmer installed on my 150G mixed reef for a week and I've already had to empty the collection cup 3 times. It's being removing over a cup of skimmate every day. It took less than 5 minutes to install and is very easy to adjust.
<br />
<br />The only con so far is that it comes with almost no instructions, just a one page diagram of the parts. Not that big of deal considering the simplicity of the design, but it seems like for over $300 that could at least give you something.

Comments: Great!!.. This thing is awesome .. good price,Pulls so much nog I cant belive..The only problem i have is the pump when i unplug it to clean the cup it wont start back up untill i bang on it to get the magnet to engage again and start spining.....

Comments: The best Skimmer I ever had.

Comments: after the break in period this thing worked great lots of very fine micro bubbles i have just thick foam at the top of mine. Really easy adjustments just move the pipe down or up to adjust how wet or dry your skimate will be. i noticed you need to clean it at least once if not twice a week depending on your load. i have it running on my 135Gal. Oceanic Reef tank with a 60Gal. sump!

Comments: I had this skimmer running on a custom 60 gal nano. It dumps tons of micro bubbles into the tank. In order to run this skimmer you need to make sure that you have plenty of baffles in your fuge or sump. Even with 4 baffles bubbles were finding their way into the display. I think the pump is too large for the skimmer body. Otherwise it is a quality built product that fits into a small space. If you have more space go with a larger ASM, I have them on my larger tanks with no problems so I think it is just this model that needs some refining.

Comments: I ordered a G-6 and it had 2 not 3 pumps. I am in the middle of my reef build so I dont have it online yet but wanted to write a review to let you know how confused I was to see 2 not 3 pumps. I still think I got the right skimmer for the job, 650+ system.

Comments: I had no space in the fuge/sump, but I was able to get this in 5x5 inch space& it sucks out dissolve organics voraciously. Only complaint is the massive amounts of microbubbles it releases (the reason why it is such an awesome skimmer). Cant beat it for the price.

Comments: Super fast shipping!! Easy to use product. Sets up and is running within 20 mins. Would definetly recommend to EVERYONE!!!
<br />
<br />FUZZ

Comments: I have this on my 180 gallon reef and this thing works wonders. My tank is full of SPS and they all keep their color. I would highly recommend one.

Comments: Better than I expected. Needs to be patient. It took 3 days to "break in" this skimmer. Fairly well built. This replaced an Aqua C 120, which causes too much flow/bubbles in the sump.

Comments: I bought G-1X to replace my older Venturi skimmer. At first I wasn't sure if it was worth upgrading but now I wished I bought it in the first place. It feels very solid and very easy to adjust. Basicly plug and play. A good buy and worth every dollar. Don't worry about the extra money. When you see the performace you will be glad you bought it.

Comments: I found this product worked as well if not better than I expected it to for the low cost of item. I have had the item for over 2 1/2 years now w/NO PROBLEMS! In fact I purchased an additional one for my 750 gallon Coral Grow out system. It has preformed just as well as the other one did. I am well pleased with the results and performance of both skimmers. I wish they made a bigger one than the ASM G-6.

Comments: All the performance you'd expect from a Euroreef skimmer but for less dough. Keep it cleaned every ~6 months or so and it works like a beast. I am very pleased with this skimmer. I will probably end up dropping another one into the sump of my next reef setup as well.

Comments: I've had this skimmer for about 2 years now. It's very consistent, and I've never had any issues with it. It also skims pretty good, too!

Comments: I found this skimmer to skim very well. The pumps are reliable and there are few skimmers that can provide as much size for the dollar.
<br />
<br /> Unfortunately, the build quality is very poor. My unit leaked excessively at the base of the cone until I simply siliconed it permanently in place.
<br />
<br /> I would recommend adding a gate valve on the output to better manage the water level.
<br />
<br /> Skimmer needs to be handled carefully as it seems fragile. Still, for the price of competitive skimmers you could purchase 2 or 3 G6's!
