Aquarium Advice Freak
I have colonies of sponge and anemones growing in my canister filters. All my tanks only consist of fish and inverts .They are void of living rock and coral because it is illegal over here. Also I tried All different types of the ceramic and glass biological filter media in one of each tray in the canister filter. Not one anemone or sponge was growing on it. But the natural filter media that I use Had sponge and anemones on them,also nice copepods living in there. I think a lot of this ceramic biomedia they are selling is just high priced junk. No wonder the canister is considered a nitrate factory. I use my long tent. anemones as my water indicators and I haven't had any problems yet. So I would like to know if you think my canisters are dong there job? I also have wet and dry filters on some Tanks.
