Adf filtration?

[deranged chipmunk]

I dont buy cartridges ... I just rinse them in the water I am changing out ... otherwise you basically re- cycle your tank every time you put in a new cartridge.

I will look at those filters ... I have so much to buy already what's one more thing?

Actually, that's not true about cycling the tank. But this isn't really the place for that.....lol
