For those who want the fully DIY experience, you can pick up the Leviathan board with no pre-soldered components. This will allow you to customize your setup exactly how you want it with no additional pieces to worry about.

Going this route is the cheapest way to build your very own Reef-Pi setup. The Reef-Pi guide on Adafruit recommends about $25 worth of proto-boards. Not only is that more expensive, you've still got to hand-wire every single board connection that Leviathan already takes care of for you!

The fully featured Leviathan board comes pre-soldered to allow you to utilize all of the features Reef-Pi offers!

It is set up to: control up to 12 equipment outlet relays, control up to 4 lighting channels, monitor 3 separate temperature zones, measure water level with an optical & 2 mechanical level sensors, control 2 dosing pumps, & monitor pH.
