I do not dose calcium, but i use a kalkwaser reactor to keep my alk and ph stable seems to keep a higher calcium yet it does not precipitate (snow) Mag I seem to have to drip every second day or it drops to fast to replenish, I tried purple up and not ticed no difference, I am wondering if it has to do with the blue back color i painted in the tank, Perhaps if i painted it blackl it would be better.
Coraline that does start growing in the tank will allways go white on me, so I am at a loss how some popel grow it like crazy and some people cant..like me LOL
