I don't bother with testing. I find it far easier to calculate the dosage
I need to reach the desired level, dose it, and then let it ride. I
generally add about 0.5 to 1ppm twice a week. You can use Chuck's
calculator to calculate dosage for KH2PO4.

No. You're only after the phosphate. The rest isn't important.
