I can give only fragmentary advice on Chymistry - there are all sorts of nuances about dissolved solids levels for sustainable long term use, but for the most part it seems as if before serious spa activity you need to get the pH and chlorine/bromine levels right, and after serious spa activity you should probably change the water anyway.
