Actually was not measuring at all but just walking by the unit and noticed that on a very sunny days this was occuring. It is happening again today, another gloriously sunny day with lower humidity thanks to mild trades around 12 mph.
As you know from the many previous post you have so quickly responded to I have a Pool Pilot Total Digital; it measures and reports pH constantly sampling all the water that passes through it. Most of the water is supplied to it by my roving pool cleaner, so presumably not local.
Maybe, as stated above, this information is not useful at all but I promised Chem Geek I would follow up. Or do you think it is better not to report these minor observations? I thought the China Shop was for this more esoteric stuff, or am I incorrect about this? If so I will stop posting observations.
The great thing about this though is that I am using less acid than I did before. Einstein is quoted as saying something like (although the context in which he meant this is debated) "Compound interest is one of the great wonders of the world'.
Bearing this is in mind a small seemingly insignificant savings can add up to significant savings over time and maybe as we have many sunny days - year round, at least in my local area, this is another great reason to live in Hawaii; saving money on acid. Also we rarely need pool heaters in winter so long as one covers. The other readings remain the same.
Thank you for your diligent attention to my posts. I am really learning more about pools and internet forum etiquette from you both; but most of all about chemistry from Chem Geek, as it applies to pools, and that's great.
