Q: How much is too much stabilizer?
A: A common myth in the pool industry claims that too much Stabilizer (Cyanuric Acid, CYA) in pool water "locks-up" the free available chlorine residual. Chemically, this is not accurate. The free available chlorine residual kills microorganisms with CYA levels up to 500 ppm. Minimum CYA level is 30 - 40 ppm, acceptable is 30 - 200 ppm for residential pools.
