who uses red sea test kits (po4)

[JmeJReefer]

Been using REd Sea for some time now....one of the more accurate test kits out there.
As long as you follow the instructions to the letter, it should read accurate.
However, there is always exception. Maybe ya did get a faulty reagent.

Im sticking by mine......
