Here at Alliance UK online we stock a great selection of pool water balance chemicals from Blue Horizons. A pool that is balanced has proper levels of Ph, Total Alkanity, and Calcium Hardness. The ideal measurement ranges are as follows; Ph:7.2 – 7.8, Total Alkanity: 80-120 ppm, Calcium Hardness: 180-220 pp, Stabilizer: 30-50 ppm. Water balance condition will change naturally all the time and you should monitor pool water balance measurement regularly. We also supply pool water testing products and test equipment.
