SPACHEM Ph Down
Ph Up (1 kg)
Lowers the pH of Spa/Hot Tub Water.
Proper pH balance is an essential part of spa/hot tub maintenance. The recommended range is 7.2 - 7.8. If the pH of your spa/hot tub is high (above 7.8), the water will be alkaline & the chlorine is prevented from doing its job since it "combines" with other materials in the pool/spa water. The existence of this phenomenon is usually detected by a strong chlorine odour not found when the pH is in balance. The water tends to be cloudy & eye irritation may develop. Scale build-up may also begin to occur.
