Need some advise on water chem.

[DomC]

So I did a 10% water change on Sunday like I always do. For some reason the water got cloudy and hasn't cleared up. I had changed carbon 2 weeks ago and decided to change it last night but still was cloudy this morning. I know it has to do with the high calcium. But not sure if I should just plan on a big water change or bring the mag up a bit. any advise would be great. Mixed reef about 80% SPS.

Salinity: 1.025
Mag: 1350 Salifert
Calcium: 512 Hanna
Alk: 8.3 Hanna
Phos: .04 Hanna

The mag looks fine. Your calcium is kinda high. Dkh is where I like it to be. I wonder if its precipitation.
