Arctic Perfect Balance 1kg
If the total alkalinity level of the spa water is below 80mg/l (ppm) use Arctic Spas Perfect Balance to increase the level.
To increase the total alkalinity by 10mg/1 (ppm) use 27g of Arctic Spas Perfect Balance per every 1,500 litres of water. Run your pumps for 30 minutes and test the alkalinity again. If the level is still too low, repeat the process.
