I have a 13.5 gallon evo and I have some corals tanks been up for about 5 months now I’m wanting to dose calcium and alkaline right now my calcium is 320 and alkalinity is 161.1 ppm how is my alkalinity? I know my calcium is low I’m wanting a target of around 400-420. I have brightwell code A and code B. I’m new to dosing please help. Also I have a API reef master test kit I use to measure these.
