CYA 100
From what I understand all CYA test max out at 100 even at the pool store (if I'm wrong I'm sure someone will correct
So being at 100 means it could be 100 or 300.
You have to dilute the sample with distilled water then double/triple the result (depending how much you're diluting) to get a true reading.
