Topic at hand, let's discuss.......

We know that canister filter's in time do more bad then good if not properly maintained as they become a nitrate factory.

I personally wouldn't use one, maybe to clear up the water after setup or to run carbon on the system for whatever reason(meds or chemiclean)

But what if one used a canister filter and packed it with cheato with a light which have come across before has been effective on smaller tanks but would need a few of them to make a impact I imagine.

On larger tanks though, i would suffice to setup a refugium in a tank versus canisters but with Fish Only tanks, canisters properly maintained do work?
