When I did my set up I waited a day or so then I put in my live rock. My salinity wasn't perfect but it didn't seem to matter much my lr
is doing great and is growing tons of coroline algea. There will be some die off when you first put it in but don't worry it will grow back. Just make sure you have your heater set. I have mine at 76-78 degrees. It helps the salt desolve and stabalize faster.
