testing results

[waterbear]

You have not been keeping up with Richard's(Chemgeek's) lastest posts (then again I don't think you are a member at TFP), Recently he has some evidence that higher CYA levels offer more protection to chlorine than formerly thought. You have a CYA of 35 because you are using ORP control for your SWG, correct? If you were not you would seel the better chlorine retention you would get from a CYA of 70-80 ppm but becuase that would play havoc with your ORP controller it is not meant to be.

Once again, I say that your experience is with one pool. You have posted quite a bit of misinformation and was even called on it by one of the mods in this forum. I have answered many posts for your because you were not sure of the chemistry that was happening. Because you have a spreadsheet that you take as the gospel (it is merely a tool, btw) and have a basic understanding of how to run a pool (most of the time) doesn't make you an expert any more than being able to carve a roast makes you a surgeon.

Now if you are finished with this thread hijack we can get back to the OP and her questions.
