Re: NFC: Another Filter/Aquarium Question
Those who have wet / dry filters...are your bio balls submerged? I made a
wet / dry out of plexi and have the space for the bio balls above the sump
tank level. I thought the chemical process needed oxygen...but looking at
some wet / dry filters offered commercially the bio ball area stops only a
few inches above the bottom of the tank.
So...before I finish this thing...do the bio need...or need to not be
submerged?
Thanks,
Larry
