reconstituing ro

Question
Because of ammonia and nitrates in source water I would like to use ro but am unsure about which product to use for reconstituting minerals.  There seem to be 3, and none of them seem to provide Kh, just the Gh. One seems to have a lot of sodium and another a lot of potassium. Would a trace mineral product for the fish be necessary also? Any advice would be welcome.

Answer
This all depends on the type of fish you are keeping. You don't want to waste money trying to fluctuate k.h. levels when they really don't matter that much to most fish. unless your levels are extremely high don't worry about it..





Really hope this helps..
