Dankcichlid Posted February 27 Share Posted February 27 Im upgrading a HOB filter on one of my 55-gallon tanks. its been running for a few years, with 2 cartridges with the activated carbon cut out, ones a year old and the other was switched out a few months ago. would that floss from the 2 cartridges be efficient in keeping the cycle going? Im upgrading to the Seachem tidal 110. My plan was to place the floss in the new HOB bucket along with some new media while taking the old filter slush(?) inside and throwing it in the new. any insights or tips would be appreciated. I could always throw the new unit on the other side of the tank but would rather not break the plastic slot in the new hood i just got. 1 Link to comment Share on other sites More sharing options...
AllFishNoBrakes Posted February 27 Share Posted February 27 It’s likely that you have way more beneficial bacteria in the actual tank, than in the inside of the filter. You can most likely just swap it out, feed lightly, and test often, and not have any issues at all. 2 Link to comment Share on other sites More sharing options...

I'm nervous to do it without keeping original HOB unit on. 1 Link to comment Share on other sites More sharing options...
AllFishNoBrakes Posted March 3 Share Posted March 3 If you’re nervous, and if you can do it, run both filters for a few weeks, and then take the old one off. I know you said you couldn’t really do that, but that’s kind of your other option. 1 Link to comment Share on other sites More sharing options...
