Think of it this way....Since my tank is so small compared to the new, what do you think about putting a bunch of new filter floss into one of the media chambers so it can become backfilled with bacteria ? Almost like a live rock? Or am I being stupid. Worried that the tank won’t fully cycle properly with the amount of media, rocks, fish and coral I own already.
Since it’s been a while it’s a waterbox 10 with roughly 8 pounds or so of live rock. Charcoal, GFO, random plugs I’ve thrown to “cook”, media balls, shells and coral. Do you think that will be enough to jump to instantly cycle as long as I throw in my two clowns? I will will be implementing Carib seas life rock (not live rock) for an add on to the new scape.
Your rock, sand, media, other filters handle your livestock already. If you take all that, place it in a new tank, what changed? Same rock, sand, filters, livestock. Maybe you added new water and a couple more rocks.
Point is, your media and rock are doing the job just fine, switching to a new tank will change nothing unless you add new livestock at the same time. Which you should wait anyway.
