^^^^ what he said lol ^^^^ i personally have water around 180ppms winter and 280ppms summer, loads of calcium and goodies in the well water it would be a shame to take it all out using an r/o system.


Also to answer deftdrummers other question, yes it might be a bad idea to use the h2o2 solution becuase it kills off some good bacteria that organics have in them that plants love.
