I am currently working on setting up a 300 gallon tank which will be an upgrade from my 72 gallon reef. The new tank will start of with dry rock and sand. I want to use this as a chance to eradicate Ich from my tanks. Since I am starting off with dry rock and sand, does it make sense to set up the big tank with hypo-salinity and keep the fish there for 6-8 weeks. Or should I do it the other way around and transfer the inverts, rock and sand to the larger tank and keep the fish in hypo in the smaller tank?
