Alkalinity Balance, pH up, pH down, Calcium Balance, Water Stabilizer, and clarifier are all swim-safe chemicals. Wait about 20 minutes, and you are free to swim. We suggest adding algaecide, Super Erace, and shock at night, after everyone is out of the pool. It is safe to swim again the next day.
For most products sold by Kem-Tek, you can use the pool 15 minutes after application, as long as your pump system is operating properly, and your pH and chlorine levels are good. An important exception: When you need to shock your pool and the chlorine is increased to more than 5 parts per million (ppm). When this is happening, wait until the water is at 3 ppm or lower before adjusting or letting anyone back in the pool.
