I have a 75g tank with 20g sump. I have not added water yet. I have 60lbs of CaribSea Aragamax Select sand, 30lbs of their Araganite Seaflor Special Grade Reef Sand, and 5lbs of their Ocean Direct Caribbean Live sand. I have about 75lbs of rock that was pulled from the LFS tank and left in a box that was dry when I got it and has been kept dry since. I have a 4oz bottle of Aquacleanse(no access to RODI water) to treat my tap water before I mix in the salt. I bought a 2oz and 4oz bottle of One and Only because the dealer didn't have the size I needed in one bottle. Now, after saying all of that, come my question(s). Is the 5lbs of live sand and the 75lbs of dry rock enough to cycle with One and Only, or should I add a Clown or 2? Or should I wait to add the Live Sand until after cycle. Will that rock be fine the way it is, or will it negatively effect the One and Only? I know this may be a lot to tell and ask at once, but I'd like to get this right the first time. Thanx in advance.
