My pH readings are significantly different if I take them in the deep end versus the shallow end. In the shallow end near a jet I am getting readings of deep purple around 8 and at the deep end at around 7. I couldn't find any posts on this in any searches. Should I just assume I am in balance at around 7.5 or do I error to the readings in the deep end? This seems like a problem.
Significantly different PH in deep end versus shallow end?

sounds like really poor circulation. had the pump been running 30-60 mins when you did this? are you taking the samples 12-18" below surface? (about elbow deep should be good). what are your other numbers?
Yes, pool has been running all day and always take the readings above the elbow deep. The deep end has worse circulation for sure as the spa waterfall really moves the water on the shallow end. I usually have the returns pointing upward to shoot across the water and push leaves toward the skimmer. Maybe I should point the returns more down towards the bottom?

you have a giant pool like that with no main drain in the deep end? pointing an eye down will help increase circulation down there. there is also a product called the circulator if the pros here think you have major issues with that kind of difference. maybe it would help.
Yes, there is a drain down there but the water is definitely more still in the deep end as it looks to me like they should have put in an extra jet or two.
pH in a circulating pool should be very even and stay that way easily. I suspect some type of testing error. What are you testing with?
Could it be possible that the aeration from the waterfall elevates his Ph on that end? Granted the entire pool should have relatively the same Ph, but with the aeration only on one end it will take some time for the water to mix and equalize right?

wrong ends. it should be opposite if that was happening cause aeration raises ph and his ph is high in the deep end, whereas the waterfall is in the shallow.
Try turning off the waterfall, with the filter still running see what the pH does after an hour. Then turn the fall back on, check it again after a couple hours. If you see it even out after the fall is off, and change again after it goes back on, then the fall is really raising the pH in the shallow end and you need to improve the circulation in the pool.
