I did some aquascaping about a month ago. I took out a 4lb piece of fully cured rock as it didn't initially work with the new scape. The rock dried out for 2 days. Two minor adjustments and the piece will work again and I want to add it. It's been in a bucket of saltwater for about 2-3 weeks, with 4 water changes. My established system has about 50lbs for rock and 30lbs of sand. Thoughts on if it's ok to add to the tank at this point? Thanks.
