What start up chemicals are needed for a 25,000 gal pool?

If you're a new pool owner, one of the most important steps to maintaining a healthy and clean pool is to start with the right chemicals. Here is a list of start-up chemicals you'll need for a 25,000-gallon pool:

  1. Chlorine: Chlorine is an essential chemical for maintaining a healthy pool. It helps to kill bacteria, viruses, and other harmful microorganisms in the water. You'll need enough chlorine to bring your pool to a level of 1 to 3 parts per million (ppm) at start-up.

  2. Alkalinity increaser: Alkalinity increaser, also known as sodium bicarbonate, is used to increase the alkalinity of the pool water. This helps to stabilize the pH levels and prevent fluctuations that can cause damage to the pool equipment. You'll need approximately 10 pounds of alkalinity increaser for a 25,000-gallon pool.

  3. pH increaser/decreaser: The pH levels in your pool should be between 7.2 and 7.8 for optimal performance. If the pH levels are too high, you'll need a pH decreaser, which is typically sodium bisulfate. If the pH levels are too low, you'll need a pH increaser, which is usually sodium carbonate. You'll need approximately 2 pounds of pH increaser or decreaser, depending on your starting pH levels.

  4. Calcium hardness increaser: Calcium hardness is important for maintaining the integrity of your pool equipment and surfaces. Low calcium hardness can lead to corrosion, while high calcium hardness can cause scaling. You'll need approximately 10 pounds of calcium hardness increaser for a 25,000-gallon pool.

  5. Stabilizer: Stabilizer, also known as cyanuric acid, is used to protect the chlorine in your pool from being degraded by the sun's UV rays. You'll need approximately 4 pounds of stabilizer for a 25,000-gallon pool.

  6. Shock: Shock is an extra dose of chlorine that helps to kill any bacteria or algae that may be present in the pool water. You'll need to shock your pool at start-up and periodically throughout the season, especially after heavy use or rain. For a 25,000-gallon pool, you'll need approximately 5 pounds of shock.

It's important to note that the amount of chemicals needed may vary depending on the initial condition of your pool water and your specific pool's needs. It's always a good idea to consult with a professional or your local pool store for advice on the best start-up chemicals for your pool. With the right start-up chemicals and regular maintenance, you'll be on your way to enjoying a clean and healthy pool all season long.
