should anything be harmed from this? must have dosed a bit to much each week. In process of water change to bring levels down as I type. some corals slightly retracted.

ya, thats all that i could really think of that would be affect at these levels. the magnesium being a little higher then it should, if im correct magnesium should be at 1200-1400?, i would only think your alkalinity would be affected only a little because magnesium is a weak base, so it would make it go up. i think your are fine though. my calcium got up to 500 once and my corals actually grew alot, which i was surprised because i thought to much would affect them in a bad way. i got it back down to 420-450 and the corals are growing at a normal rate now. that was my experience. but i think you should be fine, just try not dosing the buffers for 2-3 days check the levels and decide from there if you need to stop for a little longer or start up again.

From Billy's testing when mixed to a salinity of 1.0264 Oceanic mixes up to around your levels. I have not heard about hobbyists using Oceanic complaining. ;)

Alk: 8.5 dKH
Mag: 1650

my last water change was about 2 months ago 15% using coralife salt .
No big deal i guess,I will just do 2 or 3 more water changes and stop dosing to get levels down I am just a stickler for params :)

Curious what the Alkalinity is when you're Cal and Mag are so high. Would seem to me that your pH and/or alkalinity would have to be way out of whack to support that without causing precipitation.

I agree, checking the alkalinity is important with those levels. Is precipitation ocuring? How are your snails doing?
