Stabiizer, also known as cyanuric acid (CYA) is a chemical that bonds to chlorine. The effect is to slow down it's sanitizing effects in the pool. Without stabilizer, the sun would burn most of the chlorine in your pool on a hot day. Stabilizer is like a slow release agent for your pool and is therefore a necessity to maintain chlorine levels in the proper range.
