I have been playing around with a nice quality gram scale and trying out various concentrations of stock solutions of Potassium Nitrate for dosing my planted tank. It already gets all the phosphate it needs from the soil.
Here is what I came up with.
I made a solution of 6.17 grams of KNO3 per Liter solution.
Tested it out by adding 15 ml to approximately 15 gal of actual water. The results on an API test kit were as follows.
Viewed from the side as is normal, the test showed yellow. 0 ppm.
Viewed from the top down through the liquid there is a slight orange color detectable.
This should be a great solution to make very precise additions.
Should be very close to 1 ml adds 1 ppm of Nitrate per gal. That means it also adds approximately 0.66 ppm of Potassium for every 1 ppm of nitrate that it adds.
Notes:
-I noticed 1/8 teaspoon (level) makes almost exactly 0.75g KNO3.
-KNO3 has no practical water of crystallization.
