Kinda of a dumb question but.. I took the filter media out of the sump on my smaller tank which is 175 gal with like a 20 gal sump and temporarily shut it down, the media is mostly bio balls and foam.. I put it in the 110 gal sump of my 420 gal. The 420s filter media consists of 1 large 2” thick foam pad,2 filter socks, a bunch of bio balls and matrix. My question is how long would it usually take to seed the 420s media with bb before I dare remove the 175s media and get my other tank set back up??
If you just moved half of the media, then both tanks are immediately cycled.
At my age, everything is irritating.
