This may be a siily question but.......

Ok-well I still have some ph minus from opening-so I will try that first. I added 1/2 cup to start for an 18x48 pool. I have read that if the ph gets to low it can harm the liner-so I a liitle hesitant. I will re-check in two hours. On average how long does it take for Alk to lower-is this another long process? Should I keep my filter running?

A couple more questions:

And I am still unclear about aeration.
One alk is adjusted do I add borax to raise ph back.
Can I continue to add my bleach as normal during this process?

I really appreciate your help. By next season I should be a pro!!
