Filter or no filter?

[FitoPharmer]

Just remember to replace the flow it makes since you want at least 20 times turnover in your display tank or more. Cansiter or any mechanical filtration needs constant maintenance in saltwater setups, unless you run them with only LR rubble. I would suggest ditching it as well. I had a fluval canister for a while, I did not mind it because I just filled it with LR rubble and used it as a cryptic fuge /pod factory and never opened it afterwards since it would occasionally leak after cleaning.
