well water = 800ppm
tap(municipal water) = 300 ppm
water from nearby refilling station = 60ppm

i'm having a hard time figuring out my nutrient solutions because of this.

thanks

the readings were based on available water at my disposal.

the tap water more or less 300ppm. with heavy chlorine.

i''l buy Ca test kit for aquarium tomorrow and see how much Ca it has.

i'm feeling it has too much iron due to rusted pipes.
