So i'm picking up a FOWLR tank....he treated it with the amount recommended for his system 2 years ago for ICH . I have a reef. What is my best option with the live rock...and what about the sand? Will it leach...My plans were to tranfer my 220 into his 240 using my water rock ect...but keeping his sand. I'd rather be safe then sorry. Any advice? Thanks in advance.
