Hard Hard Water

[toobefree]

I have 4 tables each with 1000 hps and 50gal nut tanks My problem is the city water is reading about 600 ppm and my plants are having Magnesium deficiency from what I can tell. I am using Bat Guano for my nut at about 1400 ppm. help.....

using guano in hydro is tough enough,but with calcified water you might get a lot of binding,solidification fungi or lock-up,I would just use chems,and keep the ph adjusted,or you might consider an RO machine,hope things work out for you....bonbon
