Dosing Nitrate calculation check

[Makara23]

I made some calcium nitrate Ca(NO3)2-4H2O solution and before I dose my tank, I want to make sure my calculations are correct so I don't kill everything:

Dissolved 232g of calcium nitrate in 200ml RO/DI, poured it in a 500ml bottle, topped it off with more RO/DI.
Dosing 10ml in a 60gallon water volume will increase about 10.7ppm nitrate and 3.43ppm calcium.

Does everything look good?

Thank you so much!

Oh also, adding water to calcium nitrate is an endothermic reaction? The solution was very cold when first dissolved, as if it was sitting in the fridge for hours.

Yes it is:
