Does rain water make pH go up in pool?
Rain almost immediately causes the pH (Potential Hydrogen) in the pool water to rise while also reducing the TA (Total Alkalinity) slightly via dilution. Higher pH will cause more of the chlorine in a pool to become inactive or “fall asleep” reducing it’s effectiveness.
Will rain water raise pH?
Rain is initially neutral in pH, a perfect 7.0 – but very quickly absorbs low pH contaminants as it falls through the sky. Such rain is not usually extremely acidic, but may fall in the 5.5-6.5 pH range, low enough to affect your pool pH levels, again causing a need to raise your pH.
What increases pH in pool?

Baking soda, also known as sodium bicarbonate is naturally alkaline, with a pH of 8. When you add baking soda to your pool water, you will raise both the pH and the alkalinity, improving stability and clarity. Many commercial pool products for raising alkalinity utilize baking soda as their main active ingredient.
What happens to the pH of pool water when it rains?
However, all rain in the US is acidic due to pollution, so rain actually decreases your pool’s pH – in other words, the pool water becomes more acidic. The pH of pool water should be kept between 7.2-7.8 because this is what the pH of a person’s body is usually at.

How does rain affect your swimming pool and hot tub?
The reality is that rain affects your pool or hot tub in multiple ways. However, this doesn’t necessarily mean that rain is detrimental to your pool; it can be good or bad. The water chemistry of a pool is very important; it needs to maintain the proper chemical levels to remain safe and comfortable for those that use it.
Why does my pool water turn green when it rains?
And it’s the only way to prevent your water from turning green or cloudy white when it rains. Here’s a quick summary of how rain affects pool chemistry: Acid rain causes your water’s pH to decrease Rainwater also decreases Total Alkalinity
What should I do with my pool water when it rains?
Safe range between 80-120 ppm. It is not uncommon to see cloudy water after a heavy downpour. Try adding a Water Clarifier to your water, which will coagulate dirt and oil that are clouding the water. It is also a good idea to add an Algaecide to your water at this point.
How does rain affect your pool water level?
Rain can be very acidic, which will quickly drop your pool’s pH level. The drop in pH will also impact the total alkalinity and chlorine levels. A pH Increaser will be needed in most cases to bring your pH level to a safe level (between 7.4 to 7.8).
What happens to swimming pool water when the pH goes up?
The power of chlorine to effectively do it’s germ-killing varies with pH level. As pH goes up, the ability of chlorine to kill germs goes down (see the scale below). Another affect of high pH is a reduction in swimming comfort.
And it’s the only way to prevent your water from turning green or cloudy white when it rains. Here’s a quick summary of how rain affects pool chemistry: Acid rain causes your water’s pH to decrease Rainwater also decreases Total Alkalinity
What should the pH balance of a pool be?
Rain can be acidic, so it can offset both your pH and alkaline levels. A pool should have a pH balance of 7.4 to 7.6, while some rainwater has a pH balance around 5.0, so heavy rainfall could lower the pH balance of the pool.
