Yesterday was the first day for the adults. Everyine that went in had red eyes. The background:
I never added CYA until I found this site. The SWG always seemed to work ts magic last year and I only had one outbreak. So, after reading this, I checked my CYA = 0.
I added about 8 pounds on Thursday and it is all gone from the skimmer.
Like I said, Friday, our eyes got really red, but it did not feel like a chlorine 'burn' when in the water.
Chemistry this AM:
Cl = 5 no CC
Alk = 110
pH = 7.5-7.6
CYA = 40
Any ideas? We are about to go back now.
