welll parrot, I made a mistake testing, .2 ml of testing off actually, which is a lot when you look at the red sea titration tests.
After learning how to do it right. My alk is above 14 dkh (i buffered that slightly) my mag has moved up to 1400 (buffered a bit today, but doesnt help that the .2 ml off is a lot) and calcium is at about 550.
So now, I am going to wait for it to drop, to about 450 cal, 10dkh and 1300 Mg and then wait 4 days, work out how much went, divide it by 4 then start dosing daily :) and like you said, test weekly from there. Then, when my tank cleans up, start adding some more sps, and redo the test
