I know these "pool store potions" are not recommended by TFP, because they are not needed with the BBB method (which has served me well since I joined the first spring in this house), but the previous owner left some. They have been sitting for years, because I am somewhat of a hoarder, and it wasn't taking up that much space, but now I'm tired of looking at it. Do they have a potential application? I hate to waste them if they do. Or should I just dump them?
