I have this saved in my notes. I think from @Randy Holmes-Farley
“Here's my standard recipe for potassium nitrate, and it can be adjusted easily up or down in concentration, as needed:
Dissolve 10 grams potassium nitrate in 1 liter of fresh water. That 10 grams contains 6.14 grams of nitrate, so that solution is 6,140 ppm nitrate.
If you add 1 ml of the solution per 2 gallons of tank water volume, that will boost nitrate by 0.8 ppm nitrate.
As a rough estimate, 10 dry mL of powder weighs about 10 g. ”
So if I mix 20 grams in 1 liter and I have 70 gallons of water volume then adding 35 ml of solution should bring nitrate up 1.6ppm. Is my math correct? Last time I tried this I dosed enough to bring nitrate up from 0 to 5ppm and some of my SPS started browning. I want to try again but go a little slower
