Pool owners need to prepare swimming pools in the event a tropical cyclone threatens the area.
There are important considerations before and after the storm to keep your system functioning with minimal problems.
First, clear any furniture and trim large tree limbs that could become flying projectiles including pool or spa covers.
It can be convenient to toss outdoor furniture in the pool for storage but be careful not to scratch the marcite and understand some materials may cause rust spots.
Add chlorine and algaecides to prevent algae and bacteria. Be sure to supershock the chemistry in case the power goes out for an extended period of time.
After the chemicals circulate for 24 hours go ahead and prevent electrical problems by shutting off the pool motor at the breaker. This protects equipment from shorts due to rising water. You may want to wrap your pump with waterproof plastic or sandbags if it is located in an area that could get submerged.
Don’t fall into the mistake of draining your pool otherwise hydrostatic pressure may crack and pop the shell out of the ground. Only drain water levels so enough can pass into the skimmer.
Once the storm passes, be sure to remove as much vegetation debris before before powering up the equipment.
Super-chlorinate the pool again and circulate continuously until clarity returns.
Clean or backwash filters often, and recharge with new diatomaceous earth. It may take a few days to get the water balanced back to normal.
