Whether you live in the sunbelt or the snowbelt, closing your pool correctly is an important and easy process that will elongate the life of your pool.
- Adjust pH to 7.2-7.8 to prevent stains, scaling and algae growth. Shock the pool using label directions.
- Run the filter for 24-48 hours.
- Remove floating debris and vacuum thoroughly.
- Add an algaecide to prevent algae from forming before water freezes.
- Follow your pool manufacturer’s directions for lowering your water level. Only a few pools need to be completely drained during the winter. Many pools fare cold temperatures better when partially filled with water as a buffer. A drained pool can also crack or pop out of the ground because of pressure from ground water.
- Shut off filter pump and drain pump, filter heater and all other equipment. Store to prevent freezing. Follow manufacturer’s directions for lubrication and proper covering(s).
- Turn off all power to the support equipment and remove fuses or turn the circuit breakers to off.
- If you have a slide or diving board, take it off and store it.
- Cover pool securely and fill water bags halfway (the edge of the cover should be sealed so that wind does not get under it). A quality pool cover resists water, weather and pool chemicals and keeps out leaves and airborne dust.
Your weather permits a longer swimming season. However, if there will be many weeks when your pool is not in use, continue routine maintenance on a reduced schedule.
- Begin by reducing filter running time in half. Keep pH between 7.2-7.8 and free available chlorine between 1.0 and 3.0 parts per million (use tester). Follow pool equipment manufacturer’s instructions for proper care of equipment during this time.
- If you do not cover your pool, clean your skimmer every week, maintain filter according to manufacturer’s instructions and vacuum as needed.
Covering your pool will keep out leaves and dirt and reduce the number of needed chlorinations. Before covering, shock treat according to manufacturer’s directions.
