Ummm I am going to ask Suz and Janny if they are online. I really do NOT know how fast the new plaster will push the ph up.

of course they are off line right now................Rock and hard place.....
Guess we will find out. I just know that I have always read that low PH is the hardest thing on your equipment BUT I am hoping he did not take it down to the danger area.
It DOES sound as if he knows what he is doing from what you wrote earlier.
I say let it ride and see what it tests as in the morning.

Oh man, the one evening I'm needed, and I'm off line. I fell asleep at 6:30 and didn't wake up this morning til 8:00. I haven't slept that long since my teens.
Now my Internet is down, so I'm stuck to my cell.
If you waited til this morning on the pH, I think that's fine. My pH has no problem rising. Like you said, Umm, I usually try to raise it first with aeration (I think I only needed to do that once - I usually have to lower the pH).
Also, with this weather front we're getting, I'm assuming you've already had the rain we're now getting in Houston. Rain will help raise the pH.
Now, my other tip from TFP which I hold on to is this. I'm more careful when adding chemicals to RAISE numbers. Especially for CYA and calcium hardness. But I think it's a good rule for pH, too, with our plaster and soon-to-be SWG pools. So if you feel the need to add borax (I used 20 Mule Team from the grocery store cuz I have it on hand for my son's smelly cigar smoking clothes - yuk), use Pool Math to determine how much to add. Then I add a little less than it says to. When I get better at all this and am more sure of my gallons, I'll be able to better target amounts needed of chemicals.
Again, for now I go easy on chemicals that are trickier to lower. I can always add a tad more after a retest.
My other tip I hold onto came from Duraleigh. I've read many of his posts. My favorites of his stress to focus on keeping the chemical numbers within the TFP ranges. After a month or so, I started looking at the CSI numbers and getting all worried over those. Now I simply glance at the CSI numbers, but my main focus is on keeping the chemical numbers in the TFP ranges - Pool School gives you all those. There's more to learn from CSI numbers but that can come later and from the experts.
My other tip from TFP I love is to relax and enjoy taking ownership of your pool and water. For me it's a very empowering feeling. You won't destroy your plaster with one bad test reading. It's like a temperature reading for a person at the beginning of a cold. "Oh, it's rising a little or a little too low. Ok, no big deal, I'll just check Pool Math or Pool School and adjust (like with Tylenol)."
Or," Wow, the test (thermometer) says the chemical is really out of range. Ok, I'll ask TFP (the doctor) and find out just what to do. All will soon be well. "
I may be giving tips you don't need, but oh well... That's what old ladies do, right?!!
Just relax and enjoy your new pool ( or new baby)!!
Suz.
