Rendezvous Alkalinity Up 1lb
Granular additive raises spa water alkalinity helping maintain pH levels.Features:Effective water balance controlApplications:To Increase Total Alkalinity:Determine the level of total alkalinity. If the value is below 75 ppm, add sufficient ALKALINITY UP directly to the water - to increase the total alkalinity value to at least 75 ppm.2-1/2 tbs. will provide approximately 10 ppm increase in total alkalinity for 500 gallons of water.Wait several hours for ALKALINITY UP to distribute uniformly before rechecking total alkalinity level. Repeat as necessary.Tips:After adding ALKALINITY UP, wait several hours before rechecking total alkalinity level.Compatible with chlorine, bromine, ozone and biguanide sanitizers.
