As fall approaches each year, homeowners begin to think about winterizing their pools. If you have a salt water pool, you may be wondering if there are any special steps you should take in addition to normal winterizing techniques. The steps to winterizing a salt water pool are really not that different than those for winterizing a traditional chlorine pool. The main difference lies in balancing the chemical levels of the water before closing it up for the winter.
Using a pool water testing kit, balance the chemicals by testing the following levels: alkalinity, pH, and calcium hardness. If the levels are too low, add additional chemicals available from any pool supply company.
If you see any green algae anywhere in the pool, remove it with a pool scrubber and add an algae treatment to the pool water.
Thoroughly vacuum the pool and clean the pool filter.
Run the pool filter and pump for one hour to circulate all of the chemicals.
Drain the water level in the pool to approximately four to six inches below the skimmer line.
Install the pool cover and secure it using tie downs or water bags.
Turn off the pool pump and the electricity to the pool.
Set the pool filter to the "winter" setting if it has one. If the filter does not have a winter setting, set it to neutral. Open the filter and allow any water to drain out. Leave the filter cover open to allow excess moisture to evaporate.
Pull the plug out of the drain pump, and suck out the remaining water in the pump with the pool vacuum. You can also simply leave the cover off, and allow this water to evaporate as long as the temperature isn't near freezing.
