I'm in the process of building a new stand and canopy for my 125g. I'm wiring the lighting/pumps/timers into the canopy so that only one cord will come down behind the tank. And mount and bind all the cords to the things in the refugium under the stand so that only one cord comes out. I will have an easy access emergncy cut off switch for each. I'm thinking this will clear up and simplify things a bit.
