High pH is not just a number on a test strip: it makes the water uncomfortable on skin and eyes, drives scale onto your heater and jets, and blunts the sanitizer you already paid for. The sodium bisulfate granules dissolve quickly with the circulation running and work alongside chlorine, bromine, biguanide, silver mineral, and ozone systems. Keep a bottle on the shelf so you can correct pH the same day your test flags it.\u003c\/p\u003e\n\n  \u003csection class=\"spaphdn-spec-section\"\u003e\n    \u003cdiv class=\"spaphdn-spec-heading\"\u003eSpecifications\u003c\/div\u003e\n    \u003ctable class=\"spaphdn-spec-table\"\u003e\n      \u003ctbody\u003e\n        \u003ctr\u003e\n\u003cth\u003eManufacturer\u003c\/th\u003e\n\u003ctd\u003eHaviland Consumer Products\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eBrand\u003c\/th\u003e\n\u003ctd\u003eSpaPure\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eModel \/ MPN\u003c\/th\u003e\n\u003ctd\u003eC002625-CS20B8\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSKU\u003c\/th\u003e\n\u003ctd\u003ePST-SPA2625CS20B8\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eUPC\u003c\/th\u003e\n\u003ctd\u003e025551701251\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eProduct Type\u003c\/th\u003e\n\u003ctd\u003eSpa and hot tub pH reducer (dry acid)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eActive Ingredient\u003c\/th\u003e\n\u003ctd\u003eSodium bisulfate\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCAS Number\u003c\/th\u003e\n\u003ctd\u003e7681-38-1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eForm\u003c\/th\u003e\n\u003ctd\u003eDry granular\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eNet Weight\u003c\/th\u003e\n\u003ctd\u003e24 oz (1.5 lb)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTarget pH Range\u003c\/th\u003e\n\u003ctd\u003e7.2 to 7.6\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDosing (pH 7.7 to 8.0)\u003c\/th\u003e\n\u003ctd\u003e1\/4 oz (2 tsp) per 500 gallons\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHigher pH Readings\u003c\/th\u003e\n\u003ctd\u003eFollow the dosing chart printed on the product label\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eApplication\u003c\/th\u003e\n\u003ctd\u003eAdd while the water is circulating, then retest before adding more\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSanitizer Compatibility\u003c\/th\u003e\n\u003ctd\u003eChlorine, bromine, biguanide, silver mineral, and ozone systems\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSignal Word\u003c\/th\u003e\n\u003ctd\u003eDANGER.
