I'm curious. If you had to take a guess, how much money have you spent on this addiction? I'm just looking for a ballpark figure. You don't have to include the increase to your water or energy bill (unless you want to). The day I left to go pick up my current tank (29 gallon), my wife sent me with $150. I didn't tell her but I knew in my head I would spend more. At this point I don't think I've broken the $1000 mark yet but it's got to be close.
