I added a 2213 enhiem to my 20g high. I still have the old HOB filter running as well. My question is how long should I keep the HOB running in tandem with the canister filter to prevent any cycling issues? Any tips or insight would be appreciated.

You could take all the media from the HOB filter and just stick it into your Eheim 2213 to avoid this altogether.

Otherwise, you should keep your HOB filter running for at least 2-3 weeks.

be carefull when you do finally make the switch because when i removed my hob i killed all my shrimp and almost all my fish due to co2 poisioning. the dramatic decrease in surface agitation was enough to put my diy co2 into gas chamber mode. :proud:
