I was setting up my QT this weekend, and the lady at the lfs
recommended I use a bio-wheel filter since there would be no LR
(or anything for that matter) in the tank.
I read up on these little bio-wheel filters, and they sound pretty cool! The amonia and nitrites are processed in the wheel.
I'm considering replacing my wet/dry with one of these for my 42 gallon display tank.
Anyone out there use bio-wheel filters exclusively?? Would I need an additional PH
since the bio-wheel filters simply let the water 'fall' back into the tank?
