They do the job well. Api and salifert are the only tests I trust to use while housing 1000's of $ of coral.

This is the best kit for daily use to monitoring phosphate content in foodstaff. Extremely easy to use. The result reliability sits between the expensive photometer device and the color sticks kit. Both of thise two methods have fatal shortcoming for use in the kitchen. A photometer is rendered nearly it useless as it requires a perfect clear liquid which is impossible with foods. The simpler sticks are way inaccurate/biased, thus almost useless. By comparison, this API kit tolerates minor cloudness of the test liquid which is easily achievable by letting it settle until a relatively clear supernatent appears at the top layer to be analyzed.

Does exactly what its supposed to do. Gives you an accurate reading of phosphates for water tests.
