Review on 🐠 Efficient Aquarium Maintenance with S.T. International Aquarium Surface Skimmer by Zoey Vaughn

To use it with the Fluval AquaClear 70 I had to use a small strip of neoprene to make the diameter big enough. Also, I had to put a sponge around the bottom water intake otherwise it would suck in like any other water intake for example roast or moss. I also have an AquaClear 70 in the tank and this sponge inlet goes all the way down too. So I filter on three levels. HOB = hang on behind.
