Yeah, I think this could go one of two ways....
1) Is too much CC and (maybe CYA) allowing the fishy smelling cooties to be growing in the water. If the itching is confined to the uh.... uh...... you know that area down south between Mittgaard and Sommersonnenwende, then I lean toward #1.... or,
2) Is too much TC and (maybe CYA) making the water smell that "bad pool" smell (chloramines). If you have the all over itchies and maybe red eyes, I lean toward #2....
I say all of that to say this: "I'd stay out of the pool until we get all this sorted out....." But, either way you are going to have to perform a SLAM and you might as well read up on that while awaiting the test kit's arrival....
