Do I need a filter pad If I have a foam-Prefilter?
Hey guys. Quick question. I'm running a planted 10 gallon nano with just 3 ottos and some cherry shrimp. I have an aquaclear large pore foam pad with a hole cut it it and the filter intake inserted into it. the foam pre filter is new, but once it becomes established with bacteria, can I take the whisper cartirdge out of the filter? I'm running 100 ml of Purigen in the filter along with the whisper filter cartridge, and it's packed in there! Ineffiecient filtration. I know the jury is out on Purigen, but it's gonna stay :-) lol.
