ESHOPPSNano Skimmer | Protein Skimmer for Nano Tanks | New improved adjustable magnetic mount | Adjustable water height. Minimal foot print. Fits most All in one tanks back chamber

The media could not be loaded. I purchased this skimmer because I was getting tired of replacing the wood air blocks used with the air pump driven nano skimmers like the bio cube protein skimmers. I started off with the highest pump setting but it spit out lot of micro bubbles the same is said for medium flow. So I dialed it all the way and gave it the 10 day break in time and it produced skimmate no problem. The noise level is not that bad but it is noticeable and after a while you block it out. What I dont like is that it was designed mainly for rimless tanks. How ever I was able to get mine to fit below the rim of the aquarium. I am using this in a JBJ 29 gallon nano aquarium (modified). I give it a 5 star overall because it is working the way I want. I would have loved to have room to put it in the back chamber of the aquarium but there is no space. Seeing it in the tank is unfortunate but I sacrificed aesthetics for the need to filter my aquarium. I would buy this again I needed in the future.

Worked well for about a month, then barely made any bubbles/skimmate after.

Adjustable . Reliable . Great value for what you pay . Did tons of research and this one works like a charm . Produced great skim mate within a week or two (less) break in time , 0 micro bubbles in tank . Waterbox 20AIO fits in rear sump . Would try there other products too ...

This replaces a hang on Aqua C Remora. I like the Eshopps clear collection cup better. I wish the collection cup had a drain connection because getting it off to empty it and then putting it back on is a pain. I trusted other reviewers who said constant water level is a must and put it in my constant water level, hang-on-the-back, CPR Aquafuge. It was extremely quiet initially but after a month the pump became loud enough to keep me up at night (the tank is in my bedroom) so I have a controller automatically turn it off at bedtime and turn it back on at 6 am. While it doesn't produce anywhere near as many bubbles as much more expensive units do, it does a great job of collecting the dark green "tea" despite being off for about 6 hours a night, every night. I need to empty the cup every 2 weeks. It's in 4 gallon hang on refugium which is on a 16 gallon tank that's jam-packed with corals, crabs, shrimp, snails, stars, and 4 fish. I tend to overfeed and use a Neptune DOS to do a 1.5 gallon water change 6 days a week. On the plus side, it fits into very tight spaces and is very easy to clean and maintain. Also, with the included sponge in the bottom of the tube, no bubbles make it back into the tank ever. I keep the top of the powerhead just slightly above the water line. I would have gone with the Tunze but it didn't fit where the Eshopps does. If you want the show of seeing lots of bubbles in the tube, you'll be disappointed. If you don't care about the show and just want it to pull out lots of dark green tea and you have a constant water line, it's perfectly fine.This is probably the best skimmer for putting inside a CPR hang on refugium.

Great skimmer for a 10 gallonWouldn’t use it much for a 30 gallon or a 35It did fit in my innovative marine nuvo 10

Great little guy! As is normal with nano skimmer the skimmed material is never too dark but it works great and create heavy foam when I need it to! Also the magnet to hold it in place works great and is super strong but you have to put it so the brand name goes in ( the label doesn’t show from the outside). Lots of reviews said the magnet is really weak and I agreed until today by accident I flipped it around and it’s amazing and very strong! Oops haha

Like me, if you have a 4" chamber in an AIO tank (i.e. NUVO 25g lagoon, etc), this newer version of the skimmer is larger than the description details (nearly 4.5"). With the magnet mount removed, it's exactly 4" but the skimmer without the magnet is then a pain in the arse since the cup would be the only thing keeping the skimmer from dropping into the chamber. I can't convince myself to remove the entire skimmer to empty the cup every couple of days.Only other option is to put the pump beneath the skimmer and run a line to the skimmer inlet but nope, this pump doesn't have enough head pressure. Need to upgrade that but will anything fit? The frustration.Two stars because while testing in the display, it skimmed really well right away. Oh and the magnet is now strong.

Update: Customer service is ok. They sent new magnets and parts for the pump to keep it quiet, but this thing really is more hassle than beneficial. The height adjustment is the problem. Adjusting it millimeters causes it to go from dry skimmate to overflowing with water. I'll be contacting them to return and provide an update on how willing they are to work with me on the return.I'll keep this review updated, but 5 days in and I'm not loving this. Although the air drive is silent, the pump itself is incredibly loud. I'm assuming this is because the magnet isn't very strong, so there's a lot of vibration. When I physically hold the unit again the tank with a lot of pressure, it's completely silent. Because the magnet is weak, the unit keeps slipping down or to the side. Many people say their unit broke in a day or two -- I'm seeing no progress so far. I was also disappointed with how little instructions there are. Others might be satisfied with the simplicity. I've contacted Eshopps to see if they can offer solutions, so I will update on their response. I'm hoping for a positive customer service experience.At this point, the only thing I'm loving is the size. More updates coming...
