Even with an automated dosing system, regularly check the peroxide level manually with Hydrogen Peroxide Test Strips. The additional measuring cups and our manual will allow you to accurately calculate the peroxide level in your Epsom salt water.
Applied immediately in the water, the test strip results are affected by the high amount of Epsom salt. Using the dilution ratios provided (the instructions for this are added with the delivery of this kit) along with the measuring cups (set of three included), the strips give an accurate indication of the peroxide level in your Epsom salt water.
Range of the strips: 1 - 100 ppm.
Note: The peroxide level should never drop to zero.
