Review on 🧼 12 Zanyzap Foam Filter Pad Inserts for Hagen Fluval 204, 205, 206, 304, 305, 306 (A-222) by Robert Decamps

Exactly as described, pre-filter for Fluval 206 (which is what I use). After the test I have only 1 negative comment. These filters are not as free flowing as flow filters. I installed my CO2 atomizer above the tank and before I switch to this filter the current would reach it and blow the CO2 through the tank. Now I see that most of that CO2 goes up into the tank. Because of this filter I have to rearrange the CO2 atomizer. That being said, these filters are really handy since they are pre-cut.
