From this thread as a reference, https://www.reef2reef.com/threads/dosing-monosodium-phosphate.314502/

Na2HPO4 - 141.96 g/mol, PO4 - 96 g/mol
So each g is ~67% PO4.

If you add 3g Na2HPO4 to 1L RODI, you will have a stock solution of 2mg/mL

Convert your tanks water volume to liters, and then determine the dosage from there. Example, if you have a 100L tank, and add 1ml, would have added .02 mg/ml, or .019 ppm PO4

Someone should definitely check my math though, I haven't finished my coffee.

I wish this was more clear- So what IM gathering is to mix up the solution with the rodi water and the sodium phosphates then dose the tank from that? with just 1ml at a time?

Not 1 mL, but some amount you determine.

use the calculator and associated directions. The potassium phosphate entry will be close enough:
