Magnesium level

[Dmmz]

I got a magnesium test kit today and brs 2 part i did my test and mag was 200 I did test again and test was the same. I use reef crystals and do weekly 20% wc the 200 ppm does not seem right to me thanks for any help

Doesn't seem right to me either. What test kit are you using? Is it old? Try testing using another kit and if the results are the same just start dosing Mag :)
