Will do the water change and see how low the mag went down.

Have you tested your Alk since you raise the Mg so high?

One thing to remember - you shouldn't raise MG levels quickly (by more than 100ppm per day) - so therefore you shouldn't lower it too quickly either!
Small water changes daily to bring it back down

If you're Mg is 1650 and one water change is going to bring it to 1350 then you're not adjusting your parameters appropriately. You should always be raising or lowering your Mg, Ca, Alk, SLOWLY. Lowering it from 1650 to 1350 in one day is much too fast.

I'd leave it along for a while, just carry on with normal water change schedule(if you believe in water changes :lol2. People purposely raise Mg to over 1600 in hope of getting rid of hair algae, I have not read anyone nuked a tank from it.

You should use Salifert or Elos, Red Sea test kits are junk.

ditto. i had my mag up in the 15-1600's for a while due to my stupidity ....wrong dosing calculations. if i remember correctly, you shouldn't raise or lower mag more than 100ppm a day.
red sea test kits work just as well as my 7 yr. old.'s chemistry set.....lol.

alk at 10.5
mag at 1400
cal 480
the only reason to keep mag at 1400 is to keep cal and alk stable.hight mag will not hurt anything

OK Ill wait for the next water change. I just thoght that in i do one more water change it might go back to were it need to be. I been doing my regular water chage 20%
