Re: Getting itching rashes after swimming
Nobody called you ignorant--I guess the "chip" is the one on your shoulder. JohnT told you EXACTLY what I would have told you: Post your numbers, FIRST, then let's see.
99.99% of the time, there's something in the numbers the poster didn't see, but someone else does. And the solution is usually pretty simple. But once in a blue-moon there's a head scratcher.
We are all here to help each other, but nobody can help you with your problem if we don't have complete information. We ALL start there when we have a problem, even if we've fixed it but are wondering how it started. We don't just put up numbers, we explain what we have done--trying to give whoever is reading it a CLUE to an issue we are not catching.
We start by eliminating the obvious: A problem in the basic numbers. From there, we move on to other possibilities.
You say your numbers are "fine". What does "fine" mean? Some of our users like to run with CYA=60 or 70. For them, they feel that's "fine". But for me, that's most definitely NOT "fine". We have an honest disagreement about what "fine" means.
We'll do what we can, but you, on your side, have to do your part, too. That means posting numbers--complete information. Without that we cannot help you.
At the moment, my hypothesis is that your chlorine levels are off and something is contaminating you and your pool with an irritant. A further stretch of the hypothesis is that you need to shock your pool, and shock it good to destroy the contaminant. If I see your numbers and I see something that says that is possible, I will say so. If I don't, I'll say so too.
