After a previous thread, I have concluded that I will use coral coloration abcd from redsea. Since magnesium is basically always added separately, what is left is pH, Alk, and Ca. The methods for adding this that I found are kalk and 2part.
Based on what I learnt, kalk also helps reduce precipitate phosphate (on top of my GFO) The question I have is what's the difference between them? I will add kalk to ATO, (my tank has a lot of surface that are blown with a fan so evaporation is decently quick, so evap as a control is not as limited. But two part would need me to get an extra doser... which is annoying...
