Sodium Nitrate dosing - reasonable source?

[Wilz]

Considering dosing sodium nitrate to bring nitrate level above 1 ppm - does this supply seem suitable at 99.5% purity?

It is likely fine, yes.

Thanks Randy!

I am planning to make up a stock solution from the following recipe that I came across:

Since NaNO3 is 73% NO3:

- 73 parts nitrate, 27 sodium
- 100 parts nitrate, 37 sodium, 137 total
- 1.37 g raises 1000 l by 1 ppm
- 0.137 g raises 100 l by 1 ppm
- 0.137 g per ml
= 13.7 g/100 ml stock solution​
