This product disperses rapidly to establish a chlorine protection quickly. It stabilizes pool water and extends the life of the disinfectant. Use a reliable test kit to determine the stabilizer concentration in the pool water. Follow the included chart to bring the pool water to the desired range of 40-100 ppm. If the pool is new, just refilled, or has no stabilizer; add 4 oz. of this product per 1000 gallons to give the desired range of 40-100 ppm. Add this product slowly into the skimmer, or if desired, premix in a pail of warm water and then add directly to the skimmer. Be sure the filter is clean. Recirculate the water continuously for 24 hours to dissolve completely. Always maintain the chlorine residual in your pool at 2.0-4.0 ppm and pH at 7.4-7.6.

Not a fan of the Robelle brand stabilizer at all and will not purchase again. It did raise my CYA, but it took days to dissolve inside the sock in front of my jet return (google “the sock method” if you’re lost). The granules are kind of big and take a while to dissolve. DO NOT dump this product into your skimmer!! It is thick and will likely clog it! Use the sock method instead!!I’m giving it 3 stars simply because it does work, but do not test your CYA for at least a week after it dissolves!! Yes, it takes forever to show up on a reliable CYA test, and you could end up adding too much if you aren’t patient. I would skip this one unless you are on a budget and already have at least some CYA in your water already since this one likes to take it’s sweet time…

Works great! Put in an old sock and tied it shut. Put in my filter basket. I only used about 1/2 cup at a time to make sure the levels didn’t go up too much.
