So I am having a problem with the water I am using. The water I access is very hard and I think it actually may contain lead/rust in a rather large amount. I have a dwc setup and the res gets black resin coating the entire bottom. I have been getting ro water but I do not have access to it at all times. I know that they make nuts that are for hard water but I do not want to get new nuts when I have a large amount left. Does anyone know anything to add to the water to make it a little less hard? I know you can put espon salt but I was wondering more along the lines of h202 or something along those lines. Ideas?
