Hi, noob here. Been reading and gathering lots of good information here. Just started using my TF100 test kit and am trying to get off the dichlor/trichlor/CYA train, or as I call it, pool crack. Drained and refilled HALF the pool over the weekend, yes, ~13,000 gal. out of a total 27,500. (The governor will be coming to see me after my water meter is read.) Here are my current readings:
Yes, these are after replacing half the water. Pool store had me add 34 lbs. of baking soda two weeks ago, that's why I'm here. Pool is still green and cloudy, but the algae seems to be getting under control. Any suggestions as to where I go from here? We'd like to be able to swim this weekend (July 4th) so any serious shocking might have to wait until Monday.
I know I need to get TA down. I just added 3# of dry acid yesterday, dissolved in a bucket to get pH down from 7.8. Wife was complaining of burning skin but pH was 7.5 when I checked it. Not sure if she swam too soon (like an hour later).
Can I add more dry acid so soon or will it do any good to start aerating at 7.5? Any guidelines on how much to add per day/week, and how long to wait before swimming? Thanks for all the great advice.
