How to Balance Your Pool for Closing
Thinking about closing your pool this winter? Before you throw the cover over it, you should take a few minutes and make sure you understand how to properly prepare your pool for closing.
The first step to preparing your pool for closing is to get the water chemistry balanced. We recommend bringing in a water sample to our retail location for a free water analysis, but if you cannot bring us a sample to get it tested, you should make sure your water is balanced according to the following levels (modeled after the Suggested NSPI Standards):
- Free Chlorine: 1-3ppm
- Total Chlorine: 1-3ppm
- Combined Chlorine: < 0.2ppm (this is the difference between your Total Chlorine and Free Chlorine)
- pH: 7.2-7.6
- Calcium Hardness: 200-400ppm
- Total Alkalinity: 80-120ppm
- Cyanuric Acid: 25-75ppm
Balancing your pool is essential to doing all you can to prevent discoloration, algae growth, or other water clarity issues over the winter.
After balancing the pool, you should double shock your pool the night before closing (or superchlorinate your pool if you have a salt generator). This will help stunt the growth of algae over the course of the winter months when the pool is not in use. Using the recommended dosage of algaecide after shocking will also help prevent algae growth.
Once the pool is balanced and shocked, the next steps are to winterize the equipment and close the pool. For detailed instructions on how to winterize your equipment, we recommend calling or stopping by our store and speaking to one of our pool experts or pool technicians. If you are not comfortable closing the pool yourself, we offer pool closings where a service technician will winterize your equipment and close your pool. You can even schedule a service call for us to balance the pool for you!
