After a lot of questions and reading I finally have my Reef-Pi setup. Did some 3D printing to try and get a little fancy. Figured I would show it and see what else I can do with it. Still need to add a PH setup to it but I am quite happy with it! Does as much as any of the other controllers on the market (although I am waiting to see when Conductivity and ORP will come out!). And yeah I need to do some cable management still! lol
