pH / Alkalinity Increaser 500g
Life Spa pH & Alkalinity Increaser increases Total Alkalinity and pH in spa and hot tub water.
Water low in Total Alkalinity can corrode equipment, etch some spa surfaces, cause skin and eye irritation in bathers and excessive chlorine usage.
Adding 18grams of pH & Alkalinity Increaser to 1,000 litres of water will increase Total Alkalinity by 10 ppm.
Always dissolve increaser in a bucket of water prior to adding to spa.
Run filter for 1 hour after adding solution, re-test after 3-4 hours.
