I use well water that comes out of the tap at 8.0 or so. General Hydroponics ph Down (agricultural grade phosphoric acid) is what I use. (1/4 tsp:gallon) One gallon has lasted me almost two years, and still I have a pint or two left.

Works wonders, and the plants seem to love the extra source of phosphorous. Easy to use, too.
Rusty Trichome Reviewed by Rusty Trichome on . Hard Water?? Ok so I checked the pH and PPm of my tap water it was 8.3 and 310 ppm. Im on a well and i have seen water water high before, but never this high. What are the problems I could run into with hard water and what can I do to prevent problems. I use flora nova, sweet, floralicious plus, fox farm tripack (bloom boost). Right now I have started leaving my water out for 24 before using it. Any ideas would be great Rating: 5
