I've got a 25k gallon, plaster pool in So. Cal. Here's my results:

FC: 7
CC: 0
ph: 7.6
Alk: 125
Cal: 260
CYA: 25
Temp: 82

Not sure what all these mean, but Cal looks high. Cal is a problem with our water, I do know that. Anything I can do to bring it down?

The water looks and tastes great, although I do have a mustard algae problem from time to time (mostly my fault, I think). It's not a current problem.

Thanks!
