Review on EA Performance HOB Power Filter - Ideal for 4 Gallon Desktop and Betta Aquariums - Non-China Manufactured by Erica Gutierrez

Have owned several aquariums in over 20 years. I've been using it for almost 30 days. This filter is no better or worse than comparable products on the market. The best I can say is that it's quiet while in use and the cord is nice and long. Cons - still leaves a film on the surface, turn it up for good flow and it craters in the bottom substrate - to avoid disturbing the substrate I have to turn it down to almost a trickle and then there is no water movement below the surface. Although it may not use "special" filters, the filters used are not available to me locally.
