I've decided to use a free-standing lamp right next to the tank. I'll put a dimmer switch on that lamp so I can gradually let the light wake everyone up. This new lamp will also be lighting the new 10g tank I picked up today which will sit right beside the 29g.

I hope to reduce the occurence of diseases by reducing their stress in any way possible
