DKH is your alkalinity which usually doesnt effect magnesium. Limewater can in small ways, but magnesium keeps your calcium from preccipitating out of your water. Is your calcium high at all? Maybe you should stop dosing for a little bit, your call though.

IMO, 250 ppm of mag. is very low....should be around 3 x your cal. what is it now and why do you want to drop it so low ??

IMO, just do water changes with a mix that gives you good levels....anything that lowers Mag. will most likely lower other hardness minerals as well..
Just wondering how it got that high then....

Good question.....I have dosed in months for mag because the salt mix was with a high value. Only thing I did differently was realized after 1 year or more of using the same Calcium test(seatest) that it was 200ppm off..under I mean so I had to raise 200ppm. That was really it. :scared:

I tested a new batch of my salt today for Mag. and it come up as 1421.5 PPM
and that was at 1.026. So it is kinda high...actually it right on. So why did it get to 1600PPM??? Good question right.

If you were or are dosing, then most likely whatever you are dosing raised your magnesium. Now that built up in your aquarium to the point where it got kind of high. With the fresh stuff you might not want to add anything and just pay attention to your calcium and alkalinity and then test it a few weeks down the road and see if that helps. Your call though.
