Im filling up my tank with RO/DI water right now and am about 3/4 of the way there. I have a 90 gallon DT with a 30 gallon sump. I know I have to add the salt and get the salinity right but do I need to have any of the other parameters of the water down to a Tee before I add my live sand? I have the carribsea aragalive
