So to counter the temperature decrease do you rely solely on the the pH increase to keep CSI happy? Do you adjust TA at all in winter? I think I remember you saying you don’t add TA increaser at all ( yet your TA is at 80). ?

I can't find the post that this relates to but I know you said you let your pH run higher in winter.. to what? 8.2?

That's why I bought the PH20. I think it's cheaper than a replacement tip for the 60

I know ORP probes do not have a long life expectancy but what about in line pH probes?

Have you noticed any difference in readings in where you retrieve your sample? My first sample was at surface level and the second was at arm's length in the water. The second seemed to be where I was expecting the value to be. Does this make sense?

Where do you buy your calibration solutions from? Do you renew every six months?

Do you know if there’s an expiration date on the calibration solutions?

It is mind boggling how the ones that work in the industry are the ones that seem to be most misguided. I'm still undecided on this. Is it a deliberate ploy to sell more chemicals or is it genuine ignorance as to how pool chemistry works? If there was only one fact that the pool shops should...

Do you replace the tip regularly? How often does this have to happen?

OK, Thanks for that. So would a change in the TDS have much of an effect? Where I'm going with this is I'm thinking my pH issue from the other thread is to do with me over reading the pH. According to that chart a TA of 53 and a pH of 8.0 has a perfect CO2 equilibrium. I tested my water tonight...

The chart at the bottom of the pH TA relationship wiki is based of a CYA of 30 ppm. https://www.troublefreepool.com/wiki/index.php?title=PH_TA_Relationship How much different would this chart be with a higher CYA? in particular, 65 ppm.

But you turn it on occasionally to keep a minimum FC!?

So when you say that you add acid less frequently in winter, is this because the pH rises slower in winter or is it because you don't mind the pH being slightly higher in winter? Is it that you want the pH higher to counter the CSI change due to water temp?

So do you regularly test for TA? I read in another of your posts somewhere you don't add any TA increaser? What is your fill water TA?

What would be the problem if the CSI was acceptable but the CH was greater than 500?
