That's where the pixies live.

Ok, sorry...that's the resistor pack from which one wire goes to the
LED panel and most of the rest to the electrodes on the side of the
fresh-water tank.  There are one or two extras meant for water tanks
with more lights in the panel and hence more electrodes in the tank.

These may be of some help.
