Great info. This clarified a lot of questions I had, especially about managing pH and alkalinity in warm weather versus as cold weather approaches. If I’m getting this right, manage with lower alkalinity (and increase CH to keep LSI balanced) in warm weather to lower pH ceiling and thus reduce need for a lot of acid, increase alkalinity and allow pH to rise prior to shutdown anticipating cold water. Also, higher pH generally is not necessarily bad as long as LSI stays in balance. Makes much more sense to me now. Thanks!
Hi Joe, thanks for your comment. That is exactly right, higher alkalinity and CH will help your pool manage cold temperatures way better and prevent problems during the winter. In warmer water lower alk will put a lower ceiling in the pH. That is an A+ on today's comments.
I've got a black bottom pebble finish pool and have had so many issues with the finish. My pool company says my chemicals were not being properly balanced therefore there were calcium spots even though my LSI is being kept perfectly balanced. Their recommendation was to keep my calcium no higher than 300 and alkalinity at 90-100 but this has me constantly adding acid every few days and guess what? The calcium spots are no better! Chasing the PH is driving me crazy! any recommendations?
Generally you can maintain balance (as long as you have the pH ceiling in line with LSI too), but balance is not the only thing that matters in water. Disinfection and water quality are even more important. What we teach is how to have both at the same time. Best of both worlds.
Why are your LSI calculator results so totally different than using Pentair's LSI calculator with the exact same parameters??? Why such a huge discrepancy???
@Orenda Technologies thanks but there is still significant discrepancy between your calculator and Pentairs and Bob Lowrys formula and factors...wayyy too much variation to know which is actually correct....🤷♂️

Following LSI regardless of what chlorine one uses will still balance year round, versus following industry standards, correct?

Why doesn’t your app have an option for entering Borates? I have 50ppm in my salt water pool but don’t know how much to correct for it.
Standby for our 3.0 update release next month…
