Did it on the Biocube. A 10000k potentiometer is connected to the V+ signal off the driver. Use 2 pins on the potentiometer - the center and either the left pin or the right pin. From the pot, it then goes to the positive pad of the LED. Dims right down to zero and is a cheap solution.

Just received 9 more drivers and will work on the lights for the 90 gallon when I get some time.
