My Magnesium is really high though for some reason . I tested it 2 times and came up around 1600 both times . Donít know why itís so high when Iím not even dosing it nor done a water change in a longtime . It just started doing this like week ago

You have to pull the colony out and look on the underside of the colony. Monti Nudis are almost never visible from the front/top.

That does look a lot like monti eating nudi damage. Had some years ago. Your montis look healthy except where the damages is. If you have good eyes, reader glasses, or magnifying glass you should be able to spot them on the underside in the day, or night and early morning right on the damage line.
They are nearly translucent and small..
Good luck at finding the problem, those are nice healthy looking pieces.

Well a friend came over to look at the coral better and he said corals are not bleaching itís tissue dissolving away do to alk swing which I did have when I started my calcium reactorup . It went from 10.0 down to 7.6 in 3 days then I turned my doser back on to get it back to where it was and that caused the problem

Yup. Need, ideally, to monitor pH in reactor, effluent rate, and measure alk daily until it is reliably dialed in. You may be able to eventually stop the dosing, but wean it slowly. Avoiding big shifts in Alk and system pH are key. Don't give up on it tho, it will be worth it in the long run.
