I used to maintain the cold water tanks when I worked for the biology department at Camosun College years ago. The stuff was really cool, and surprisingly colourful. I found the only problem was working in the tank; the water was so cold my arm would hurt before it was in the tank a minute. That, and the octopus kept running away. :biggrin:

Japarto will also tell you that unless you're around all day to watch it, it would be more trouble than it's worth.

the problem with using a fridge to make a cooler is that the compressors comenly used in fridges have around a 15% duity cycle. that means that they can only run 15% of the time so say 10 min every hour. if you run more than this it will burn out the compressor in no time at all.
