Relax PH Minus Granules 

WHAT DOES PH MINUS DO TO HELP ME?

• Rapid Dissolving granules to reduce ph levels in your hot tubs. 
• The ph of your spa water is much more important for chlorine than it is bromine. The ph needs to be kept between 7.2 - 7.6 to ensure optimum conditions for the chlorine or bromine to kill unwanted pollution.

• If the ph rises above 7.6 reduce it by adding ph minus eat a rate of 11 grams per 1000 litres
