About this item
  • Effective pH Reduction: Specifically formulated to lower high pH levels and help reduce Total Alkalinity (TA) levels - preventing cloudy water, scale formation and poor performance of sanitisers like chlorine and bromine.
  • Prevents Unstable pH Levels: Stabilises pH levels, reducing the risk of bather discomfort and ensuring a balanced water chemistry. Ensures clear water by preventing scale formation and cloudy conditions enhancing the swimming experience.
  • How To Use: 1) Test the water to determine pH and Total Alkalinity (TA). 2) Pre-dissolve the pH Minus in a clean bucket of water and add slowly and evenly to the water. 3) To reduce pH readings, add 500g of this product per 50,000 litres of water, which will reduce the pH by 0.2.
  • How To Use: 4) To reduce Total Alkalinity readings, add 750g of this product per 50,000lts of water, which will lower the Total Alkalinity by approximately 10 – 20ppm. 5) Add one dose of pH Plus at a time and always re-test the water after 12 - 24 hours to ensure thorough mixing. Ideal pH range is 7.2-7.5.
  • Safety Rules: 1) Always keep the container tightly closed. 2) Keep out of reach of children. 3) Store in a cool, well-ventilated area. 4) Wear protective gloves and face and eye protection.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
