Canuck AquaTropix Posted January 28, 2022 Share Posted January 28, 2022 We just noticed that pour Fluval 406 canister filter stopped working late last night due to a power outage. When the power came back on the impeller must have jammed. It hasen't worked for about 17 hours. Is the beneficial bacteria still alive? It it safe to turn it on without cleaning out all the media?
