I'm a big believer in QT'ing, and I'm glad you are too!Interesting, I don’t have much Marco rocks in the tank, it helps build up a colony of bacteria and I like to seed the biospheres for when I qt my fish and corals. I do the TTM and prazi pro + metro/focus soaked pellets over a period of 1-2 months.
But I did add a **** ton of biospheres to seed so I can use them when I qt more livestock. So they won’t permanently live there forever.
I only added 20 pounds of sand and it’s a very minimal aquascape. So in this case is it okay to have a lot of biospheres?
I'm not an expert in QT'ing, but because I use a medicated, copper based QT, I like to use plastic bio media. I always suggest keeping some plastic bio media running in most reefer's display tanks for when they may need to get a hospital tank up and running on the fly. I say "plastic" media because it's inert, and doesn't interact with the copper medications like rock, sand, and at least some ceramics can do.
I know there's a lot of paradigms out there for QT, but I follow the R2R approved QT protocol found at this link. I always suggest this because the expert(s) that wrote and maintain this thread are right here on R2R if you need help. I know that Jay H. recently updated this protocol with some options to shorten the otherwise lengthy QT time frame, though shortening it is not without risk:
