How much H2O2 for my Hot Tub or Pool

Red Barn Farm normally has the 0-100-200-300-400 PPM test strips for measuring hydrogen peroxide levels for your tub or pool.

It covers the lower end, 100ppm, for daily maintenance and the upper level of 400ppm for shock treatment.

If you use H2O2 for awhile it will become an easy task to get the right PPM without too much work.
