In the past two years I have dealt with the following issue in the spring when I open the pool up. I go into the fall with Stablizer in the 20-30 PPM range and in the spring I have zero stablizer and I have to use a lot of chlorine to kill all of the ammonia that is there from the degradation of the stablizer. My Question is what can I do to avoid the degradation of the Stablizer that is present when I close so I don't have the mess I have had the last two springs?
