i agree 110% with Lucky. what i don't get is how, as Lucky says, it's so obvious that, for SOME questions, the asker didn't even search for a key term of their question...like, for example, chlorine. or hard water. or overwatering. the forum is SO EASY to search i just don't get how/why someone wouldn't search it first, especially, if, as some of you note, the situation is to them dire.
