20ppm Magnesium 0-10ppm Ca
Should I be concerned about using simply GH booster to raise my calc back up? Will the increased magnesium be a problem? For ever 10ppm ca. I'm adding I'm putting in 2.5ppm mg so to hit my target of ~20-30ppm ca I'll be sitting at 25ppm Mg: 30ppm Ca. Is that a problem for plants?
The water Q report shows:
only 11ppm Ca
77ppm kH (4.2 german degrees)
100ppm GH (5 german degrees)
How the hell is the pH so high but the kH and GH so reasonable? Do they ad NaOH to the water?
EDIT: Now that I think about it after Cation exchange treatment the water outted is probably extremely acidic so they probably add NaOH to keep the pipes from dissolving. And then as gas is lost the pH climbs up to what's shown right now...
I don't understand how the Calcium levels are so reduced? I think they're using some kind of cation exchange system at the water plant that pulls Calcium and not magnesium. Regardless, once I run it through my treatment system I get about 5-6pH and near 0 Ca and unknown Mg (probably less than 20).
