How Do I Clean My Swimming Pool After it Rains?

Since rainwater and pool water are more or less the same substance, it’s tempting to assume that rain has no real impact on your pool. Unfortunately, this isn’t true. Rainshowers require a special round of cleanup afterwards to keep your pool in optimal condition. Once the rain stops, get out there and run through these four steps to make sure that your pool stays clean and stable after the rain.

1. Skim and Vaccuum the Pool

Rain often leaves behind a lot of dirt and debris in pools, so cleaning those up is the first thing you’ll need to do. Start by removing the large pieces of debris (such as sticks, leaves, and large bugs) by hand with a net skimmer. After that, you can take out your pool vaccuum and clear out any sediment that may have fallen to the bottom. Doing this will also help get rid of some of the extra water that has fallen in the pool.

2. Drain Some Water

If there’s still excess water in the pool after you’ve finished vaccuuming, you should start draining out the rest. Pools are designed to help clean themselves with the skimmer system, but they can’t do that if they are too full. You’ll need to make sure that the water line is low enough to allow debris to make it into the skimmer baskets as intended – once it’s at that mark, the pool be able to perform basic cleaning on its own again.

3. Look Out For Algae

Algae is one of the most persistent problems that many pool owners have to face: it only takes one spore for an entire colony to grow and make your pool green, slimy, and decidely unappealing to swim in. Rainstorms make it easier for these spores to spread, increasing the chance that some will land in your pool and start to grow. If you see any signs of this happening, it’s best to deal with the problem immediately. Clean off any spots with obvious growth with a pool brush, then shock your water (preferably using chlorine shock). This will kill any algae currently in the pool and give you a fresh start at keeping those spores out.

4. Test Your Water’s Acidity

Once the pool looks more or less the same as it did before the rainfall, it’s time to check whether its pH balance has been thrown off due to dilution from the extra water. Use a pH test kit for precision and make sure that you get the same pH readings after a period of heavy rain as you did before that rain fell. If you don’t, adjust the chemicals you are using to get as close to that original level as possible. This is critical to ensuring the water stays sanitary and that it doesn’t have any negative impacts on your swimmers.

A little rain won’t significantly hurt your pool, but giving it the proper attention after a shower will go a long way toward keeping it usable over time. Take the time to clean it up when it rains and you’ll have far fewer time-consuming hygiene headaches on your hands later on.
