ADDING STABILIZER (CYANURIC ACID)
If the stabilizer test shows that the level is low (below 30 ppm), stabilizer needs to be added. The quantity can be determined from with our stabilizer calculator. New pools and pools that have been drained need to be stabilized. Existing pools usually only require a top up of cyanuric acid. Never neglect the stabilizer, or you will waste huge quantities of chlorine.
