If you decide to close your pool for the winter, there are a few steps you'll need to take before doing so. The procedures you do will depend on what type of swimming pool solar covers you have.
When it comes to winter swimming pool covers, mesh and solid are the two most common types. These covers have their own strengths and weaknesses, so you will need to change the way you cover your swimming pool accordingly.
Top off your pool with a mesh swimming pool cover
Since mesh covers allow sunlight and rainwater to come into contact with the pool during the winter months, it is recommended that you visit the pool at least once a month to prevent algae buildup. Do chemical treatment.
We also recommend keeping the pump running throughout the winter months to prevent a buildup of dirt. It is best to run the pump long enough for all sections of the swimming pool to pass through the filtration system at least once. You should check your manual to find out what time it is.
Topping off your pool with a solid swimming pool cover
These covers are usually opaque, which means they don't let light in. This lack of light prevents the buildup of algae, so maintaining your swimming pool will be easier and less time-consuming. Simply turn off the pump and motor put a device inside the skimmer to protect it from cold water, and then flush any excess water out of your plumbing system. You should also chemically treat the pool to balance calcium and alkaline levels.
Keep an eye on the weather
Winter weather can be unpredictable at the best of times. One day it may snow and rain and then the next day it may be sunny. However, if you're not prepared, these situations can wreak havoc with your pool, especially if you have mesh swimming pool covers.
Heavy rain can dilute the chemicals you've added to kill any algae. It is important that you monitor the weather so that you can rebalance the chemicals inside the water when needed. This process will save you a lot of trouble when it comes time to re-open the pool.
