So I have to go for a RO unit then. Is there some alternatives to RO? I don't quite sure that rain water will do in my area since I live in the middle of pulluted Bangkok. Well....need to invest!

How about if I keep on with the KH/pH lower products like Tetra's? Does it actually reduce KH or just give out strong acid? What is its disadvantage apart from its price?
