Swimming pool has very clear water but requires lots of acid and some small spots algae growing?

- High pH levels: When the pH level of your pool water is too high, it can cause the water to become cloudy and milky. This is because high pH levels make the water more alkaline, which can cause calcium carbonate to precipitate out of the water and form scale.

- Low chlorine levels: Chlorine is a disinfectant that helps to kill bacteria and other microorganisms that can cause pool water to become cloudy. When chlorine levels are too low, these microorganisms can start to grow and multiply, which can make the water cloudy.

- High bather load: When too many people are swimming in a pool, they can introduce body oils, lotions, and other contaminants into the water. These contaminants can react with the chemicals in the pool water and cause it to become cloudy.

- Organic matter: Organic matter, such as leaves, grass, and insects, can also cause pool water to become cloudy. When organic matter decomposes, it releases nutrients that can feed bacteria and other microorganisms, which can then make the water cloudy.

Algae growth:

Algae can also cause pool water to become cloudy. Algae are microscopic plants that can grow in any body of water, including swimming pools. They thrive in warm, sunny conditions, and they can quickly multiply if the pool water is not properly treated.

How to prevent pool water from becoming cloudy:

- Maintain proper pH levels: The ideal pH level for pool water is between 7.2 and 7.8. When the pH level is too high or too low, it can cause the water to become cloudy.

- Maintain proper chlorine levels: Chlorine levels should be maintained between 1 and 3 parts per million (ppm). When chlorine levels are too low, the water can become cloudy and allow bacteria to grow.

- Limit bather load: When too many people are swimming in a pool, they can introduce body oils, lotions, and other contaminants into the water. These contaminants can react with the chemicals in the pool water and cause it to become cloudy.

- Remove organic matter: Organic matter, such as leaves, grass, and insects, should be removed from the pool on a regular basis. This will help to prevent the growth of bacteria and algae.

- Shock the pool: Shocking the pool is a process of adding a high dose of chlorine to the water. This will help to kill bacteria and algae and prevent the water from becoming cloudy.

How to clear up cloudy pool water:

If your pool water has become cloudy, there are a few steps you can take to clear it up:

1. Check the pH level and adjust it if necessary.

2. Check the chlorine level and adjust it if necessary.

3. Remove any organic matter from the pool.

4. Shock the pool.

If the water is still cloudy after following these steps, you may need to hire a pool maintenance professional to help you.
