Well, I needed a case of wine and guess what, one of the pool stores is just down the street. Time to see how their testing compares to mine again.
CYA Not tested (it was 40 the last time I tested, but we have had a lot of rain)
I was told it was perfect, don't change a thing. The do their testing with Taylor reagents, same as me. The guy testing in newer, but has been around a while. He took his time and was methodical, probably why the numbers were so close. Come summer when their is a line out the door I think the speed will change.
A couple of things I noticed on the report.
They have reduced the CYA level they recommend. They used to say up to 100 was OK, now it's 50. But, sitll no relationship between FC/CYA. They still recommend FC 1 - 4.
