I'm using the acid / aeration technique to drop the TA levels. The acid part was easy and I dropped the pH down to 7.0 - 7.2. TA was at 180 when I started the process.
Now I'm aerating the pool by injecting air into the skimmer. I'm able to roughly control the amount of air back at the pump by using the intake valves for the skimmer and the floor intake. I can see air being mixed in at in the pump and I can clearly see streams of bubbles coming from the returns and I'm getting quite a bit of surface breakup. However, I'm not seeing any measurable change in the pH after running overnight. I've been running this setup for approximately 12 hours.
The pool is an 18,000 rectangular diamond bright. Are there any guidelines on how long / how much aeration it takes to achieve results?
