im michael i am new to salt but have fresh for years. got tired of looking at pics for background so started doing cement first was my 29 gal
. after that went so well we moved some fish from 55 to 29 and broke the 55 down. The 55 will be our saltwater. In the cement i used crushed oyster and large rock salt same mix for rocks. so the whole tank is / will be live rock plus hides all of the tubes . right now she is still releasing lime and ph is high , I think i have about 2 weeks left.
