Review on TOM Aquarium Canister and Power Filter Surface Skimmer by Koller Products by Hayden Tang

It works very well. I have it in a 130 gallon tank with a turtle, they are EXTREMELY dirty. As a result, the water surface was perfectly cleaned. after several modifications. First, the slots are too small. So if you go around and break off every second one, it will open up more, giving you a better chance of removing the waste. Also, take a file and smooth the edges of each hole. , the hard edges don't break the surface tension of the water so it doesn't start to flow. Another good option is to give the float a few *hard* smacks with your finger to release some air from under the cup. This then floats perfectly on the surface and glides properly. In general. DON'T SPEND MONEY ON THE FLUVAL VERSION! THAT IS THE SAME!
