How Does Rain Effect Pool Water?
There is no avoiding the rain when it comes in the summer. With that being said the extra water can affect your pool water and mess with the chemistry. It can make your pool unsanitary and potentially even cause it to lose its visual appeal. The problem lies in what comes with the water, not how much rain water there is. Algae and other debris are carried with the rain drops and are deposited into the pool. Algae spores are always floating in the air and can be carried in the wind. They seek out damp places with standing water, and your pool would be a prime target. During the rain these spores get rinsed into your pool water. Spores that are attached to any plants or vegetation also get rinsed off and tend to make their way to your pool.
How to Prevent Disaster
When this toxic mix of algae other debris get into your pool water, you must take care of it quickly. It can call cause chemical reactions with the chlorine in your water to make it less effective. What needs to happen to fix this is that you must kill algae in your pool faster than the rate that it is reproducing. This means purchasing algaecide and keeping its level at a high range. Algaecide does not decompose in chlorine or sunlight, so it will keep killing algae as long as there is enough in the water to do so. After every rainfall, test your pool water to make sure that your chemicals are in balance. If not, then add the right chemicals to get it in balance again.
Other Ways to Protect Your Pool
Another way to protect your pool during the bad weather is to secure any yard furniture or other loose objects. During rainstorms, there is often a lot of wind. These items in your yard can get blown into the water. That may not seem like a problem, but those items are often dirty and will bring that dirt into the water. There are some people who even place them in the pool on purpose before a storm to protect them from blowing around the yard. This is a bad idea, and finding a way to secure them is the much better option.
As you can see, rainwater is not a good addition to your pool. It can provide a breeding ground for some nasty materials that can make you and your family sick. Test your pool regularly to keep your water well balanced to protect and fight against these contaminants before and after rainwater gets into your pool.
