I guess buy the distilled water or RO and add the micro nutes like cal/mag.
WashougalWonder Reviewed by WashougalWonder on . Need to buy water, what do I look for ? I have been using RO water due to well problems. My unit is on the fritz and I need to water . Tomorrow I plan on going to town and purchasing 10 galons of water. Which should I buy , if it's distilled I k now to ad cal/mag to it or should I purchase those large 5 gallon drinking water bottles? I do not know if the drinking water has been softened using a salt system or when it says spring water how much processing has been done to that . Rating: 5
