Thanks! I really appreciate the help I get on this forum! I always look here when I am not sure of myself, you do a great job for us pool owners. I will try to be patient, that's difficult for me! ha ha! I will go get some bleach today. I have only used 6% bleach in the past but I saw online that Manard's has a 12% product in a 2 gallon container for $7.48. Thought I might go that route if I can find it.
