Anyone use softened city water? I know about the 24hr set out period in an open container. I know it takes the chlorine and whatnot out, but does it do anything for the salt in it since its softened. Ive got a water bong that has a sink trap type bend in the lower portion of the tube as an ice catcher, well I have filled it to the top from the bend with ice(about 12 inches of tube with ice in it) its pipe diameter is about the size of a silver dollar, I'm explaining this for a reason, hold on. Ive filled the pipe about 3 times with ice and just let it melt and empty the lower bulb as needed, anyways you can see a salt buildup in the upper tube, not resin or whatnot, its actually salt, I'm thinking this will be a problem when I start growing, anyone know a good cheap source of RO water, Id like my own system but dont have the funds or a place or reason(fake reason) to have one installed. ANY HELP??!! HOWEVER, I do have a place after all, My room shares a wall with a bathroom and has a sing installed opposite of the wall by my door, and there is an access panel that has water lines, the cold like has already been tapped for a refridgerator in my room(it doesnt work with the water lines hooked up, so using filtered fridge water isnt an option.) I can tie a smaller RO system there but what about a reservoir to hold the filtered water in? and do they make a system I could hook up till the holding tank is full and then have like a quick disconnect fitting?
