what you need is a PH tester and PH down they are a must in almost every situation and some tap water like mine is super hard water (900ppm) and cannot be used as it can interfere with the uptake of nutrition and such...

one of the easiest things to use is distilled water but it is useless unless you also add CALMAG plus to it and i highy reccommend this stuff it works wonders.
