| The wires from the fans themselves are actually wrapped in several layers of tap to the outside of the fan housings. I did this so I had a more uniform, cleaner look. The only exposed connections are the blade connects, but they are high up under the tank itself. In there locations I am not worried about to much moisture. In my experience shrink tubing works for the most part. The best way is probably to solder the connections, then cover with shrink tubing.
