Thanks Weezard! Reading through your index of info helped a lot!! I sit my water out over night because of the house plants I have..they can't take the amount of flouride in our water. So it was suggested to me to let it sit out..will have to research this further..I do know that my peace lilies have done poorly since I began this and these were the flowers I read can't take the fluoride! Go figure! lol I've peeked at a few other websites but some seem....hostile to new growers..I'm more a lurker anyways lol Thanks again..
