Calcium nitrate usage in place of KNO3?

[diazman]

Hi all, would like to seek views on your usage of calcium nitrate as a source of N? Using liquid fertilizers is burning a hole in my pocket and thinking of swapping to dry alternatives..

Your input is highly appreciated

Would be a good alternative, other than liquid KNO3.
But Ca will raise gH so you may want to keep tabs on it if you keeping high grade shrimps.
