I accidently left my Calcium doser on and it dosed half a liter of ATO proessentials into my 250g System. SPS dominant tank. Before I full fledge panic. Did I completely crash my system? Any tips on what I should do? Testing to see what ALK/CA is at now.

I think you are lucky that you overdosed Calcium part, not dKH.
I think your corals should be fine. BTW-do you like to keep your alkalinity that low and Mg high? You might consider partial water change. What salt brand are you using?

Yeah super lucky it wasnt ALK. I know my tank would have been fried if it was that.
I hate my MG that high been trying to get it to lower. I usually like to be right at about 8.5 alk, 450 CA and 1450 MG. I dose ATI pro essentials and its made my MG creep up. I do water changes sometimes but not much and use Instant Ocean.

Not familiar with ATI pro essentials , but I wonder if part 1 and part 2 is balanced as you seem to have high discrepancy between Ca and dKH. I assume you dosing equal amounts of both parts.

Yeah dosing equal 2 parts so not sure why things fell out of balance and was doing small changes to bring them back into balance. I dont like making big changes and let doser do its thing and make small adjustments as needed.

I'd just turn off the calcium dosing for a while. 
The magnesium is excessive, but is likely test error unless you have dosed huge amounts.

Yeah im not sure MG has been steady high for some reason even before the Ca OD. I turned CA dosing off last night and kept ALk on. Morning test showsI'd just turn off the calcium dosing for a while.

6am test shows:
Alk 8.21
CA 524
MG 1783
Going to do a water change today in case trace elements are too high.
