First of all I would like to say that any help is greatly appreciated, like the title says my water is coming out of the tap at 220 PPM and I'm a newbie and unsure what to do, is it going to hurt anything? So lets say im trying to mix a nute. solution with 500ppm do I do 720 to compensate for what was already in the water when I started, What I have already done was just mixed a batch to 500 total just to be safe but this has been eating at me and I would really appreciate a solid answer. thanks a bunch
