I get that, but just not sure how long people usually keep them in there. One week? Two weeks? Months? I'm sure there are a lot of variables. Mines been in the tank for 3 days. Tank has been running with 4 lbs of live rock and 30 lbs of dry rock and 2" sand for 8 days now. Its a JBJ 29 rimless with a 10g sump. I'm not seeing any ammonia yet on the test kit. I'm wing patience and not rushing anything. Just learning a lot and reading daily.
Well, there really is no anwer for that. You can actually leave it in the tank the whole cycle, the bacteria will grow enough to get everything in line.
Its best to keep it in a small net though, that will make clean up much easier for you if you leave it in there for 6 weeks.
