We had a good rain a few days ago. Apparantly rain provides good aeration, as my PH is back up to 7.6

My youngest daughter and I got in last night, and I was suprised at the amount of carbon dioxide still being released (you can see it if you wash the air bubble release after a dive or jump in). Apparantly, 7.6 is still low enough that carbon dioxide does not reconvert to carbonic acid.

I'm about 2.5" low on my water level now (we didn't get that much rain, and desperately need it ), so I may be forced to fight this battle again soon.
