Comments: I have the AquaticLife mini on another nano and it works well with the extended air line mod, but I bought this one since it got good reviews and was a bit smaller. Ran it for 3 weeks and then returned it. Cup would usually fill up in a few days, but only produced clear, wet skimmate no matter how I adjusted it. Also not manufactured as well as the AquaticLife (parts made of thinner plastic and fit somewhat loosely together). The AquaticLife is $10 more, but worked better for me.

Comments: works awesome on my wifes 28 gal nano cube

Comments: After trying many skimmers for the JBJ 28g tank, this one is the winner. If you remove the elbow return it fits perfectly in the stock skimmer chamber without ANY modification to the stock configuration. The price is right, the performance is great, and it runs almost silent. While rated for slightly less than the volume of the tank, if you do routine water changes this unit is a perfect match to your tank.

<br />If you were looking at other skimmers, here were my beefs .... the stock skimmer didn't pull enough (and the collection cup has to be removed to open the hood), the Sapphire skimmer did a good job, but the company folded and the unit took up the center chamber (and the collection cup has to be removed to open the hood). The Tunze 9002 did a KILLER job but completely took up the center chamber (and the collection cup has to be removed to open the hood). HOB models were loud and had to be seriously modified (although the AquaC Remora was by far the best)

Comments: Well I waited a month and a half before I made this review. I built a hang on refugium on my 20 long and built some space in it to house the skimmer. It took some adjusting to get it running right but once it was I was collecting waste that looks like green tea. Now my bio load is not that big. The only thing I have a problem with is that the collection cup is too small. When I check it in the morning the collection cup is completely full. All and all the skimmer does what it was made to do and does a great job for the price.

Comments: I bought this skimmer thinking it would have poor performance but figuring I could modify it and make it work well.I found myself not needing to modify it at all. It skims well, but there are a few draw backs.First draw back is like others have mentioned it is difficult to get adjusted just right. Another draw back is that the collection cup is small and will need emptied often. The biggest draw back though is that the skimmer mounts inside the tank.

Comments: it was a good buy it does all what you need it to do. the only thing that was a little tricky was trying to get the water level right without the collection cup filling up with water. but other than that it works great!!!

Comments: This skimmer is the only one that works on my 21 gallon TruVu hexagon tank. It doesn't spread any bubbles in my tank unlike the AquaticLife Mini Protein Skimmer which spreads micro bubbles all over the tank. Maybe if you have a sump which I don't have it would be okay as the sump dissipates the bubbles. I'm getting a good load of organic waste in the cup. Just need to make sure I keep emptying the cup after a few days as it is a small cup.

Comments: This skimmer operates well, creates good froth, and is very quiet. Good for small reef tanks; however, I would like to note that I purchased this for a JBJ 12 Gallon Nano Cube to place in the middle rear chamber; however, to make it fit, I need to modify the casing a little (cut off the suction cup holders (using just the hang on holder), and re-position the air intake tube)). Also the water outlet tubing can not be used as it would not fit in the chamber.

Comments: This skimmer is great and easy to use. I installed it into the back of my 12g nano and within the first 24 hours I had dry skim. I removed the suction cups so that I could fit it into an area that consumed less than 1/4 of the rear chamber. There is an open close valve to help adjust the water level. You can also adjust the height of the outflow by removing or adding lego like extensions. This sump is an excellent product for nano tanks.
