Getting close to adding water to new 170gal tank. Ideally, I would prefer to fill with RODI (not expecting major issues with leak testing) and then add salt after I see all plumbing tests put okay, mixing salt directly in sump / DT. 150 gal DT, 75 gal Sump, 20 gal Ext Refugium.
The question I have is if I go this route, I would still like to first add live sand (Special Grade Arag-Alive! Reef Sand - CaribSea) along with my Marco aquascaping rocks. Will the pure RODI harm the live sand while waiting for the following salt mix?
