Steps to acid wash inground pool without draining water?

Acid washing an inground pool without draining the water involves several steps to ensure proper and safe cleaning. Here are the steps you can follow:

1. Safety Precautions:

- Wear protective gear, including goggles, gloves, and a respirator or mask, to protect yourself from acid fumes.

- Ensure adequate ventilation around the pool area to prevent the buildup of acid fumes.

- Keep children and pets away from the pool area during the process.

2. Test Pool Water:

- Use a pool water test kit to measure the pH, alkalinity, and calcium hardness levels of the water.

- Adjust the pH level of the water to be within the ideal range of 7.2 to 7.6 before proceeding with the acid wash.

3. Calculate Acid Amount:

- Determine the amount of muriatic acid (hydrochloric acid) needed based on the pool's volume and the pH level.

- Follow the manufacturer's instructions for the correct dosage and dilution of the acid.

4. Prepare Pool Surface:

- Remove debris and dirt from the pool surfaces, including walls, floor, and steps, using a pool brush or vacuum.

- This ensures that the acid solution effectively reaches all areas of the pool.

5. Add Acid Solution:

- Slowly add the calculated amount of muriatic acid to the pool water while stirring gently to distribute it throughout.

- Pour the acid directly into the pool, avoiding contact with pool surfaces and equipment.

6. Circulate Pool Water:

- Run the pool pump continuously during the acid wash process to circulate the acid solution and ensure even distribution.

- This helps to remove stains and scaling from all surfaces.

7. Monitor pH Level:

- Check the pH level of the pool water periodically during the acid wash process using the pool water test kit.

- Adjust the pH level by adding a pH decreaser or increaser as needed to keep it within the ideal range.

8. Brush Pool Surfaces:

- Use a soft pool brush to gently scrub the pool walls and floor to remove any loose debris and help the acid solution reach all areas.

9. Allow Acid to Work:

- Let the acid solution circulate and work for several hours or overnight, depending on the condition of the pool.

- The acid will dissolve stains, scale, and mineral deposits.

10. Rinse Pool:

- After the desired time, neutralize the acid solution by adjusting the pH level back to the ideal range.

- Rinse the pool thoroughly by running the pump and refilling the pool with fresh water if needed.

11. Rebalance Water Chemistry:

- Test the pool water again and make any necessary adjustments to restore the water balance, including chlorine levels, pH, alkalinity, and calcium hardness.

12. Wait Before Swimming:

- Wait at least 24 hours after completing the acid wash process and rebalancing the water chemistry before allowing swimming in the pool.

Note: Acid washing should be done cautiously, and it's recommended to consult with a pool professional or refer to specific guidelines for your pool type and materials to ensure proper and safe procedures.
