TriSodium Phosphate food grade mixing

[Marc2952]

i bougbt this from amazon a while ago and wanted to know if any of you guys use this? And if so how much do you need to add for 1 gallon to bring up the phosphate 0.01 per 1 ml like some other brands do? Doesnt say the purity in amazon but since its food grade my guess is that its fine?

Calculations will fail because much of what you add will bind to rock and sand.

But this calculator is a good way to gauge what to dose (say, 0.02 ppm per day for a few days and see what happens). Use the entry for potassium phosphate and use 25% less than it says because the sodium phosphate is more potent.
