Fi-Clor pH Increaser (Soda Ash) is for raising the pH level in swimming pool water. pH is a measure of how acid or how alkaline the water is. Low pH can lead to skin irritation and corrosion of equipment.
Instructions to correct pH
Calculate the volume of water in your pool (if in doubt, consult the Fi-Clor Swimming Pool Handbook).
Take a pH reading using your test kit or test strips. You will need to raise the pH if the reading is below 7.2.
Pre-dissolve the Fi-Clor pH Increaser in pool water using a suitable container. In order to avoid concentrated solutions, only dissolve a maximum of 500g of the product in 10 litres of water at a time, adding product to water, never water to product. If you need to use more than 500g Fi-Clor pH Increaser repeat the treatment. Dose no more than a total of 1kg at a time.
With the circulation system running, distribute evenly around the pool, avoiding the skimmers.
Continue filtration and re-test after 24 hours. If the pH is still low, repeat the dose.
