Jeff Posted April 28, 2022 Share Posted April 28, 2022 My 10g planted tank has been running for two years now. I've had an AquaClear 30 on it since day one. I'm going to switch to a small canister. After adding the canister, and while the HOB is still running. How long do I wait and how will I know when it's safe to take the HOB off, and leave the canister? Aka...how do I know there's enough beneficial bacteria in my canister to safely remove the HOB? Link to comment Share on other sites More sharing options...
