Has anyone ever used CaNO3 (I think it's actually Ca(NO3)2 ) to supply NO3 and Ca at the same time? I would be curious to know how it works and what it does to GH or KH.
I know people have used it but I have no feedback on it. I may give it a try myself at some point, do you know what % is Ca vs. NO3 so I can calculate the doses?
