Perfect for my 200 gallon spa!!! Only have to put it on the 1 disspenssing level. So it will last over 4 months. Everything worked for my 1st time mainting a spa. Tested it with the sticks, saw that it wasnt up to par, as easily outlined on the bottle. Then shocked the water, tested again, the colors all fell into the recomemnded levels. Spa always smells and feels clean, with little chlourine smell like you would expereience at bigger pools/spas.

easy to use. Change the BLUE side every 3 months. Change the SILVER side when the blue & silver ball flips completely over and the Silver side is pointing up. The working position is when both the blue & silver are both showing above the water

Excelent product for your hot tub. keeps water noticeably clear and clean. I confirmed the changes by using the same testing strips from the Spa Frog products to confirm-the levels of Alkalinity, ph, water hardness and chlorine levels. the ph was a little lower but used a ph increase product to correct the ph levels of the water.

I can’t rave about this product enough! It makes keeping the water levels good in the hot tub so much easier! I will continue to use this as long as I can to be sure we are able to use our hot tub for a long time to come!
