I have been using this product for almost a year now. I have used others, but this is the most accurate. My tank and I depend on it!
It is especially nice that you can get the regent refills instead of having to purchase a whole new kit! Remember to rotate your componants to use older first.

The Red Sea MG test kit is the best on the market. You can't beat the accuracy nor the price for the refills.

you have to follow the directions exactly in order for it to work. Add a drop then swish for 15 seconds then add the next, repeat 5 times.
