I was actually wanting to install an r/o system in teh basement for when I setup my other tanks. Will the r/o system level out the ph? Also because I rent I dont really want to have to tap into a water line unless I have no choice. Maybe something I would attach to the washer input line and have the washer attach right behind that or something. Have it fill a trashcan with a powerhead in it. Maybe setup a float valve to shut it off at a certain level.
