I have my male CT is a Tetra 3 Gallon cube tank which came with the whisper 3i filter. I want to upgrade to a better filter system. I tried the Deep Blue Biomaxx Nano, but need to buy new filter media after Hurricane Sandy interfered with my cycle. I cant find new media for this filter anywhere. Not even my LFS has replacment media, yet they sell the filter.
So I'm considering a new filter altogether. I would prefer a 3 stage filter if possible (mechanical, chemical, & biological). I'm pretty certain that all the Whisper 3i can accomplish is mechanical and chemical.....failing on the most important biological :(
