I have read a lot of posts about Tap water PPM and I get conflicting information...
I use tap water in SoCal and after I let it sit overnight or even 48hours my PPM is around 600-650! (its about the same before I let it sit as well).
Is this bad? Do I really need R.O.?
Im currently 1 1/2 weeks into veg on a flood and drain system with rockwool and clay pellets, using a 25gal res. What should my PPM be at this stage? and do I account for the tap's 600ppm when adding nutes?
Also, Ive heard some people talk about adding Hydrogen Peroxide to their res, is this common or only if you have a bacteria problem?
Your opinion is appreciated!!
