Thanks for the answers guy's. It seems that the chlorine is a main player. I don't know what else is in the water here maybe saltpeter for the marines but if I add one gallon to 5 gallons of R/O my stuff starts to yellow in 2 days. County water. I have yet to see anyone in my county use tap other than to R/O it.

In the county's next to me I see guy's growing with pure tap water and never any real problems. When I ask about bene's they say there ain't no benefits in this kind of bussiness except smoking. They don't know what the hell a bene is.

Well maybe we will see some about systems gone bad and cleaned up.
