The best option is to purchase directly from Bluefish: https://aquarium-led-controller.com/
IMPORTANT: Please fset the jumpers to 5v as described in the Bluefish instructions.
Failure to do so will result in serious damage to the cooling fan.
The Marine-Pac 3 supports the full controller only, not the bluefish mini. The Marine-Pac 3 has two channels of control. When setting up the controller select the Option for nanobox tide which shares the same 2ch configuration and lighting array as the Marine-Pac 3
