It's certainly possible. Usually, when people drop below what they should, they get lower than they think, for longer than they think. What I've told my commercial customers for years, that if the chlorine gets below 0.5 ppm (on pools with CYA=30), the pool WILL be cloudy the next day. Usually, it is.

In warm weather, pools need to be EFFECTIVELY chlorinated 100% of the time; not 95% or even 99% of the time.

I dumped 4gl of acid now to begin aerating.
Use the dilution with distilled water method to check your pH NOW!!

You do NOT want to get below 6.0 at ALL. It WILL damage your liner. If it is low, go get 10 boxes or so of borax, and add 2 to start, and then 1 every hour till you get back up above 7.0. (You have to go above 7 because your kit can't distinguish 6.8 from 5.8!)


Do i need additional acid and borax to increase borates after im done aerating and returned normal to PH
Yes. Acid use to lower pH from borax is separate from acid use to lower TA. However, any borax you've added this season for ANY purpose counts toward the total.

Hope i don't sound like too much of an idiot. I stress a lot over the pool. And am impatient. Thanks for your help
Nah, pretty much normal for a nervous pool owner.
