How did you test that level of pH? Really hard to get that high naturally.a) Should I be concerned about the high pH that was there over winter - its done deed already but how important is it to try to prevent this from happening next winter?
You must fully circulate the pool at least for 24 hours prior to taking the water sample to test. Once you start the SLAM, you should leave the filter in re-circulate until you are ready to baby sit it. DE filters clog very quickly when filtering out dead algae.b) How important is it to get the filter running with DE before I start the SLAM
Very. Get the pH into the low 7's. Watch your TA --c) How important is it to get the pH right before I start the SLAM
Yes. That is perfect.d) Am I OK to SLAM with CYA at 40?
pH tested with Apera Instruments PH60 Pocket pH Tester. Can't use kit when pH gets that high. I wouldn't bet my life on its accuracy, but it's certainly high when compared with my tap water (tap water registered at 6.8 using same meter - difference in water temperature has effect on meter but its supposed to compensate). When I bring pH down to a more workable range, I can use Taylor kit to measure pH as well. I find during the summer that the meter and Taylor kit get similar values when pH between 7 and 8.How did you test that level of pH? Really hard to get that high naturally.

Opened up today as the company that does it for me only will open for me in March as April and May are reserved for those that they have weekly cleaning contracts. I just open and close with them. Topping off water to get it up to get the skimmer going was surprised water had not filled back up to middle of skimmer after I pumped down in late January. Now I have to go find some liquid chlorine as my one full jug is probably shot and lost all its potency.Been so warm I am tempted to do it now, but its only mid-March.
Walmart and HomeDepot locally, or Amazon.What's the hot spot for CYA?
It's Amazon for the win. Here's my recent analysis for anyone who cares. Prices are as of 3/28/2023 21:00:Walmart and HomeDepot locally, or Amazon.

+1. I got mine early for $3something a lb.It's Amazon for the win
Found the 12.5% for $7.99/gallon out here at my local shop thad had none on Monday.Seeing how the spring traffic is in full effect, a couple bucks a gallon isn't worth the ride to Walmart. They're in the high $5s last I saw. Lowes was in the $7s and Home Depot was $9s.

Turns out my meter reading must have been off. I added 2 gallons of acid and brought the pH (with Taylor test) down to 7.4 (after 24 hours of pump circulation). TA is now 50. I will run with that and start SLAM. Had added 2 gallons of 10% chlorine two days ago - chlorine level was 2.5 today. Per SLAM, added 4 gallons of 10% chlorine today. Still have pump in recirculate but will add DE later today and be prepared to change it quickly.How did you test that level of pH? Really hard to get that high naturally.
