How long does it take to cycle a new filter. When I got the new today I got another HOB filter. I took the dirty filter cartridge and the ceramic rings out the old filter and put them in the new one. I put a new cartridge and new rings in the old filter. How long should it take to get both filters running at 100%. Just curious more than anything.

Split the old media between the two filters and leave them running together for 1-2wks. They will then be good to go. Just make sure the old media is touching the new media so the BB can transfer.....
 
That's kinda what I did. I left the old sponge in the old filter and took ther rings and the old cartridge and put them in the new one so they both have bb in them.
