I have a chlorinator that consistently keeps the chlorine level in my pool where I want it (about 5ppm).
While testing today I noticed that the CYA has dropped below 30 (that's the lowest level the kit measures - I don't think it can have dropped much below this).
Should I add Cyanuric Acid to bring the level up again or is that not necessary given I do not seem to have a chlorine issue ?
