If you have 28000 gallon swimming pool how much chemical needed?

The amount of chemicals needed for a 28000 gallon swimming pool varies depending on several factors such as the type of chemicals used, the desired water quality, and the frequency of pool usage. However, here's a general guideline of some common chemicals and their recommended dosages:

1. Chlorine or Bromine:

- Chlorine: For a shock treatment, you can initially use 1 pound (16 ounces) of chlorine for every 10000 gallons of pool water. For ongoing maintenance, add about 1 to 3 ounces of chlorine per 10000 gallons of water daily or as needed to maintain a chlorine residual level between 1 and 3 parts per million (ppm).

- Bromine: If using bromine, the initial dosage is typically 3 to 5 pounds of bromine per 10000 gallons of water. For maintenance, add 1 to 2 ounces of bromine per 10000 gallons daily to keep the bromine residual level between 3 and 5 ppm.

2. pH Balancer:

- pH levels should be kept between 7.2 and 7.8 for optimal swimming pool conditions. If the pH is too high or too low, it can affect the effectiveness of chlorine or bromine and cause skin irritation. Use a pH increaser or decreaser to adjust the pH as needed.

3. Alkalinity Increaser or Decreaser:

- Alkalinity measures the water's ability to resist pH changes. It should be maintained between 80 and 120 parts per million (ppm). If the alkalinity is too low, add an alkalinity increaser, and if it's too high, use an alkalinity decreaser to adjust the levels.

4. Calcium Hardness Increaser:

- Calcium hardness refers to the amount of dissolved calcium in the pool water. It helps protect pool surfaces and equipment from corrosion. The recommended calcium hardness range is 200 to 400 ppm. Use a calcium hardness increaser if the levels are too low.

5. Clarifier:

- Clarifiers help remove cloudy particles and improve water clarity. The dosage may vary depending on the product and pool conditions. Follow the instructions on the clarifier packaging.

6. Algaecide:

- Algaecide helps prevent and control algae growth. It's typically added once a week according to the product's instructions.

It's important to note that these dosages are general guidelines, and the specific requirements may vary based on your pool's unique characteristics and chemistry. Always follow the instructions on the chemical product labels and consult with a pool professional if you have specific questions or concerns. Regular testing and monitoring of your pool water chemistry is essential to ensure a safe and enjoyable swimming experience.
