You really shouldn’t use that water. I used it when I first started in reefing to. It’s really low salinity and inconsistent parameters. It also has nitrate, phosphate, silicate, all things you DO NOT want in new clean water change water. That stuff destroyed my biocube and killed so many fish and coral. So upset I followed advice saying that boxed water was good. Also you have to use the entire thing once you open it or it will be full of harmful bacteria the next time you go to use it. Trust me from first had experience and almost a thousand dollars wasted on that water... a thousand more for the coral and fish it had killed. Buy RODI from a reef store, make your own sw. I lived in PA for a decade, they are everywhere.
Nursery water also has trace nitrate and phosphates, you MUST use RODI for top off or it will be a never-ending losing battle. That sand is silicate based as well, not aragonite so it will not be of any benefit to help colonize beneficial bacteria and life. It will also give you some nastyyyyy diatoms for several months. You will need even more additional live rock due to the substrate type you have chosen. Just a heads up to be expecting that. Glad your nem looks happier this afternoon!
