Aquarium Advice FINatic
I'm new to canister filters. Setting mine up this weekend. I've read a lot of things about them and one thing that bothers me is a lot of comments refer to them as "nitrate factories" Is this true? Do canister filters produce more nitrates than hob filters? Do I need to clean them more often to keep this from happening. Is any media I can put in the filter to help?
