To make a little bit of pocket money, my dad and I service and clean people's fishtanks. We were called out to an older lady who just moved into a new house, and didn't know anything about fishtanks and needed some help. The whole setup was a mess: bodgy in-wall job, no foam under the tank, glass was cut without sanding the edges, and most of all, this horrible switch bank which controlled most of the 240v appliances within the tank. Totally flipped out when I saw it. Dad's a licensed electrician and went in to redo the whole thing. Who the hell thinks leaving 240v just twisted together in the open like that is a good idea?
