    How to neutralize no drain acid wash

    We would like to neutralize our no drain acid wash. My ph is 3 and the pool is approximately 7800 gallons.

    According to the pool calc I need 268oz of soda ash.

    The soda ash container says to not add more than 40oz at a time so should I not just dump it all in? What about aeration? I don't want to turn on the equipment and fry my heater but this seems like the way you would typically aerate...

    Should I just add the total 269 and turn on the equipment to aerate? Should I also worry about using baking soda to bring up the TA?

    Do NOT turn on pool equipment when PH is below 7.0. Soda ash raises PH and TA. It is always best to raise PH in steps. Add, brush, test in 15 minute increments to make sure you don't overshoot the numbers.
