It comes around every year, the summer sun is gone, the kids are back at school. The days are getting shorter and it’s pool closing season again. The later you put your pool “to bed” and the earlier it “wakes up” the less likely you are to have water issues during the season. The warm days after the pool is closed are the reason pools start to build Algae even before the pool seems warm enough in the spring. Before you close the pools you must
1) Balance the water chemistry: Approximately 3 – 7 days prior. This is the most important step as it will provide you a much cleaner pool upon opening. Water likes to be balanced and your equipment will last longer.
pH: 7.4 – 7.6 Alkalinity: 80 – 140 ppm Chlorine: 1-3 ppm
2) Clean Pool
Skim pool, vacuum pool, brush pool. If pool is especially dirty, has a lot of silt or a lot of algae, vacuum pool to waste (multiport in waste position). This prevents constant clogging/cleaning of filter. Brush the pool thoroughly. The pool should be as clean and clear as possible before covering.
3) Lower Water Level In Pool. ( ½” below circular pool water returns )
When using a submersible pump: simply turn off your main pump and equipment, and any time clocks controlling your equipment, and use your submersible pump to lower the pool water level to ½” under the bottom of the pool return openings.
Keeping the chemicals in the pool and shutting off the heater is a way to keep your pool open without it costing you an arm and a leg. Heating your pool is by far the most costly so even though the days are getting shorter, you will still have days that sitting by the pool or a quick dip might be nice. Now you know that it is also good for your pool to stay open too.
