Hello, looking for first hand experience on a quality source for nitrate and phosphate. Would prefer to use sodium nitrate to avoid water chemisty issues with excess potassium. I recently purchased these products from Amazon, but before I commence with use I figured it best to ask others for prior experience.
Trisodium Phosphate
Sodium Phosphate Dibasic
Sodium Nitrate
All are listed as food grade. Only concern I have is really with the Sodium Nitrate by Modernist.
According to the COA it shows some heavy metal like copper.
Perhaps im reading this incorrect.
