Calcium Nitrate

[ksed]

Can anyone verify if this form of nitrate is suitable to raise my nitrate levels?
If you look at the link below there are two forms of calcium nitrate, one has 1% Ammonium in it and the other is Ammonium free. This is the only form of nitrogen I can find here. I don’t know how pure it is . Any thoughts? On the SDS sheet it says (Decomposition products may be toxic) any concerns with this?
Thanks

I’m not sure how pure they are, and I’d prefer food grade nitrate salts, but they are likely both fine, especially if you spread out the dose.

With the ammonium one, if you dose 2 ppm nitrate, you will only add 0.03 ppm ammonia, which is ok.
