So, I just opened my pool on July 6th and my TA was measuring 250. After lowering the ph from mid/high 7's (7.6-7.9) to 7.0 and aerating twice (once with pool full of splashing kids after running a home-made aerator for a hour and again with topping off the pool with the water hose on "jet"), I'm down to 170. I want to get down to 80 or 90 before adding Borates, so I just dropped the PH from 7.8 to 7.0 (or slightly lower) and I'm currently aerating. I'm pointing the return jet upwards and it's aerating quite well, but it's also midnight and has been aerating for about 2 hours now ... should I continue this through the night or shut down and test in the morning and continue if needed?
