I have new test record and I have
Ca = 440
Mg = 1550
KH = 9
That's a lot better - are your corals responding?
The only thing I would say is that your magnesium is pretty high as well, but that shouldn't affect too much. If it were me, I'd bring the magnesium down (no more than 100ppm/day) and keep it around 1300, unless you have some reason to keep it that high.
