First I would suggest using a second DKH test but you mentioned using API and Salifert. You should test your new water for DKH before adding to display. You might have picked up a batch of salt with Higher DKH then normal. You say nothing is being doesd into the tank. The only way for the DKH to rise is from water changes. It must be the bag of salt you are using. Like the others posted low MAG will make CAL and ALK unstable.
get the mag up some more and keep it 3x your calcium and leave the rest alone for a week or two and see what happens .
how do your corals look ? if they are okay ,let her ride but that alk is high and i suspect your test kit . have it checked against another kit as its much cheaper to buy a test kit rather than keep dosing mag if the alk is testing wrong .
also dont do a water change for a couple of weeks and see what you params do .
NEW water test
Calcium= ~540... tested 2x's as well
Alk= 31.... What in the world!!! I did it 2x's and it came out the same
Mag= 2100
So what im thinking here is i got one extremely ****ed up batch of Reef Crystals.
What do you guys think? How is this possible?
Thanks again fellas, hope everyone had a good Christmas!

What I'm thinkin here is that you have a seriously messed up batch of test kits! My first reaction is that you used your test kits improperly but you are using several kits so I figure that is highly unlikely. I figured this because it was very likely, with your original magnesium level, that your dkh was 7 or 8 (rather than double that, which is what you measured). The same goes with your measurement of the RC salt of a dkh of 31. I could definitely see a fresh batch hitting 15 dkh. This leads me to believe that you are somehow doubling your test results. This mistake was commonly made with a set of ELOS Dkh kits which had incorrect directions included with the kit.
Take a water sample to your LFS and see what their results are. They can definitely confirm if its your salt or your test kits.
It may also help to mix up your salt, it is possible that it is not mixed well. This could definitely play a part in your extreme measurements.

The new water is being sat in a 5g bucket with a powerhead mixing it for over a hour so im sure that its being mixed enough. I have a couple tanks and test them all with this and this is the only one that is wacky. Ill take it to the store tomorrow and see what they come up with, but im assuming the kit is fine :/
I stopped in the store today and grabbed a new bag of salt. Im going to test again tomorrow, just did a 20g water change so we shall see if anything is going to change.
oooooo the joys of saltwater... ha
Thanks again
I will chime in as well. Mg needs to be higher. GEE! I bet you have figured that out by now. LOL. Don't sweat it. Mg takes its sweet a@@ time getting up there and it is better to bring it up slowly than all at once. I have had the same problems a couple of times over the years. PATIENCE is not something I am great at but if you take the time the problems will correct. As stated in other posts, Ca and Kh are dependent on Mg levels. Hang in and don't give up. Check your top off water and your mix for proper levels before adding them to your tank. That is always a good idea. A lesson learned the hard way many, many years ago by this old fart. Best to you.
