I do not have an RODI unit yet, I only have a 29 gallon tank with a 20 gallon sump so it doesn't cost that much to do a water change but the problem is where I get the water the have a really low salinity! At 1.020 or 1.021 so that is the salinity of my tank I really need to raise it for my corals to thrive if I buy salt mix can I mix it in with the stores water to raise it?
