To Cover or Not to Cover
There is a tendency for pool owners to want to cover their pools before a storm hits. This approach will be successful in keeping the dirt and debris out of your water during the storm, the cover itself may suffer serious damage.
It is generally easier to clean out your pool then go through the expense, time and energy of replacing a damaged cover. Safety covers can be quite costly to replace.
I have seen people who have quite a few trees in their yard cover their pools and I have seen people who put everything away and leave their pools be.
If you do decide to cover your pool, I would recommend giving your pool a good shocking (2X the normal) about a day before you put the cover on and then as soon as you can remove the cover from the pool before the water starts to turn green.
Heat can (and does) build up between the cover and the water and you will start growing algae in the water.
