High Ca and Mg, what should I do?

[salty_trout]

I use hw-wiegandt reefer salt. I noticed my water quality was just not as crystal clear as usual viewing down the length of the aquarium, so I decided to test all parameters. I recently cleaned out my sump (for the first time since starting the aquarium in March two days ago) resulting in about a 40 gallon water change. I do a 25-gallon water change every Sunday and top off with fresh RO water every morning. I noticed my chaeto no longer is really thriving anymore in my refugium as well. All fish I have are active and eating, as well as the 3 corals I have, are all opened fully. I'm concerned because I have 6 SPS-frags from WWC to be expected tomorrow.
110 gal total volume

Nitrate-0
Nitrite-0

Magnesium 1600

Those parameters aren't really that bad. What is your total water volume?

Okay that's good to hear, I didn't think they were too out of whack just don't want things to spiral out of control.

I'm not sure how often you do water changes, but if you do this is your bearing. (without dosing) Go from there.

I put in the post my routine, but a weekly 25 gallon water change. I did forget to put the phosphate level-detectable but close to zero. I do not dose any chemicals yet.
