Is there a certain window of time

[Rangeball]

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.

Just to claify...carbonic acid is carbon dioxide dissolved in the water. You alway have carbonic acid/carbonates/bicarbonates in the water...the pH just changes the proportions of each.

hope this is helpful.

Thanks, it was.

I was confusing CA, ie carbonic alkalinity with Carbonic Acid, ie carbon dioxide.

Since they both are CA it confused me

The proper abreviation is kH for carbonate hardness (the German form is used so it is not confused with calcium hardness)! NOt used much in the pool industry however.
