Question : I read in another post in this forum that "too much Chlorine can cause staining" ... Is that TRUE? e.g., Given the subjective nature of the test, my CYA is somewhere between 35-50. I always try to maintain around 5-6ppm of CL. But when we leave on vacation, I dump a bunch of Chlorine in the pool - bringing it up to around 10-12ppm - just so that when we return a week later there is at least 2ppm remaining & we don't go down to danger level of no chlorine ... Is this Wrong to do and possibly causing staining? If so, what do people do when away on vacation? A pool service or "pucks" ?
