currently i have a 55g with about 50lbs of live rock. it has been up and running for nearly 3 months now. i'm looking to add more live rock, and save some money at the same time. i was wondering if anyone has had any experience with tufa rock? i know you have to do the curing process in a seperate container and wait about 8 weeks before adding it into the tank. i want to slowly add about 40-50 lbs. in the future(about sept) i would like to begin building a reef. will the tufa rock do well in the tank?
