I have a canister for my 45 gallon, and a sump for my 90. I find that I do not have to clean the canister as often. To do it propery ( fluval 350) it takes about 15 minutes every 3 months or so. My 45 gallon sump Requires cleaning more often, and because of the plant light for my algea it gets unwanted algea groth
I ran an FX4 and FX6 on a cichlid tank for years. They work great as long as you clean them very regularly. Otherwise they are nitrate factories. I dont remember the exact amount i paid for them but I bet I had $650 in them.
you can buy pads to help with almost anything for them. Come in sheets and you cut them to size.

Have you ever torn down a tank over an issue you couldn't seem to beat?

  • If you reef long enough, this will eventually happen to you.
