Prevent Chlorine Loss from Photolysis: A Guide for Pool Owners

Pool owners can reduce the amount of chlorine that is lost due to photolysis by taking the following steps:

1. Use a pool cover. A pool cover can help to block out sunlight and reduce the amount of chlorine that is lost to photolysis.

2. Keep the pool water clean. Dirt and debris can act as catalysts for photolysis, so it is important to keep the pool water clean in order to reduce the amount of chlorine that is lost.

3. Use a chlorine stabilizer. A chlorine stabilizer can help to slow down the rate of chlorine loss due to photolysis.

4. Avoid shocking the pool during the day. Shocking the pool can release free chlorine, which is more susceptible to photolysis than combined chlorine. If possible, shock the pool at night when the sun is not shining.

5. Use a floating chlorinator. A floating chlorinator can help to distribute chlorine evenly throughout the pool, which can help to reduce the amount of chlorine that is lost to photolysis.

6. Maintain proper water chemistry. Proper water chemistry is essential for effective pool sanitation. Maintaining the proper pH and alkalinity levels can help to reduce the amount of chlorine that is lost to photolysis.
