As the weather gets cool, there are a few things that are important to know about your pool. Please take a moment to review these items that may arise during the next few months.
1- If you have a salt system, your cell has an automatic protection against cold water. When the water is cold, very little chlorine is needed. Your chlorine generating cell does not produce chlorine when that water is too cold because it is not good for the cell itself. A cold water light will illuminate when the water is too cold for the cell to produce chlorine. This is not a malfunction of the cell but a protection. When the water temperature is in the 40s, this light will come on and the cell will not produce chlorine until the water warms up and it is safe for the cell to begin generating chlorine again.
2- If you have an automation system, the system itself has a freeze protect on it. When the temperature approaches freezing, your pool equipment will automatically turn on to keep the pipes from freezing. If you notice your equipment turning on by itself, it is simply the system protecting itself from freezing and bursting a pipe.
3- Every pool has an automatic water leveler that is hooked to a water source. This water source will have a vac breaker on it at the source of the water. These can freeze and burst. It is wise to wrap this vac breaker in a towel to keep it from freezing during the winter months. (see page 21 in the owners manual to see what a vac breaker looks like)
4-As stated in #1 When water is cold, very little chlorine is needed. While in the heat of the summer many people have their cell turned up as much as 95% production, the winter months do not require that much chlorine. Turn your chlorine production down to 50% to start. If you see that your water still has too much chlorine, continue to turn it down until levels are optimal. This will increase the life of your cell and not over chlorinate the water when it is not necessary. Please note, as the weather starts to get warmer, you will have to turn the cell production back up.
5-If you have a heat pump, remember that the heat pump uses the outside temperature and warmth to heat the pool. Heat pumps should not be run in the night time during the winter months. You want to run the heat pump when the sun is up and air temperatures are in the 50's. Also, do not forget to use a solar blanket on the pool's surface to hold the heat in. A large amount of heat is lost via the surface area of the pool when not covered.
6- Another thing to note about heat pumps, they do generate a bit of condensation during the winter. If you notice wetness around the heat pump, this does not necessarily mean that it is leaking; it may just be the normal condensation.
