The few hydroponic gardeners i know just use tap water. The tap water around here is about 30 TDS. The waste water is about 37 TDS. I'll have to check the pH level of the water before and after. I was thinking that while RO water would be the best choice for hydro, since the TDS level is so low, it might be a good way to utilize my aquarium waste water. It would be a DWC, so the water/nut. mixture would have little to no contact with a source of light, thus little to no algae. Plus the wste water would be free of chlorine.
Thoughts?
