Roll KNo3 Solution

Hey guys, does anyone here make a liguid solution of KN03, per Chucks Calculator:

310 grams KNO3
1000ml of Water
Eguals .5ppm/ml for 100 gallons

I have a approx 100 gallon tank, so I would need to 10ml to get to 5ppm.

That sounds like an incredibly large amount of mixture to keep around if you're going to use it 10ml at a time. Why not make it up in a 250ml bottle with 77.5g?

Dry dosing makes a lot of sense for tanks that large. Just measure the amount needed with measuring spoons, dissolve in water, then add to tank.

That way there are no problems with storing solution.

You might have a problem dissolving that amount of KNO3 into 1000 ml of water. Why not dry dose?

3 grams will get you 4.85 ppm. That's roughly equal to half a teaspoon.
