Here’s just a few of the pool chemicals you might need to pick up after a heavy rain:
- Chlorine or Salt.
- Muriatic Acid.
- Calcium Increaser (Generally after a major storm such as a Hurricane)
- Cyanuric Acid (Generally after a major storm such as a Hurricane)
Beside above, does rainwater affect pool water?
Rainfall dilutes pool chemistry levels and lowers the readings for pH, alkalinity, hardness, stabilizer, and chlorine. Rainfall does not contain chlorine. As well, rainfall brings with it small amounts of contaminants that are washed into the pool.
Accordingly, why is my pool cloudy after a heavy rain?
With a rain storm, any number of contaminants can be washing into your pool – acid rain, pollen, insects, tree droppings, dust, sand and even phosphates. Any one or combination of these things in rain can make your pool cloudy.
Should I turn off pool pump when raining?
If your pool pump manufacturer has declared your pump is rain safe, you can leave it on in rainfall. Nevertheless, during a thunderstorm, it is highly recommended that you switch off and unplug your pool pump to prevent any costly and irreversible damages to your pool equipment.
So shock your pool and keep the pump running.
And if you’re wondering if you can shock a pool IN the rain, the answer is yes. Just remember that rainwater adds more contaminants, so it won’t be as effective as shocking during dry weather.
When preparing your pool for a storm, leave it uncovered. Installing any kind of cover across the pool will not do much to protect against dust and contaminants because storms often bring strong winds and heavy rain that can cause the cover to lift off your pool.
But large quantities of precipitation combined with an overflowing pool and poor drainage can cause problems such as flooding, structural damage to the surrounding buildings as well as out of balance swimming pool water chemistry.
Again, you need to know about the weather ahead of time: as always, you should only add pool shock at dusk or night. I hate to have to tell you this, but rain can also introduce algae into the pool. This is because there are algae spores in the air, which can attach to rain drops.
