I upgraded from a 20g to a 40g so I bought about 15-20lbs of BRS Pukani dry rock. I am trying to decide if I should setup my 20g to cure the rock or add one dry rock at a time over a couple of months to my tank. I don't care for both options since they will both take a lot of time. I would rather dump all the rock in the tank but I don't think I can do that in fear of algae, cyano outbreaks and a large cycle.

Looking for advice from anyone who has had to do something similar before.

I say throw it in a curing tank and add beneficial bacteria to speed up the process.

Put it in a curing tank first. I've been doing some research on it over at Reef Central and it tends to have a lot of dead organic matter on it. Supposedly it releases a lot of PO4. A lot of people let it sit in R/O water and treat with Lanthanum Chloride to remove the PO4. Then into salt water for a period of time.
