The setup for liquid food will follow in a later update, I am currently away working offshore in AngolaCame here to see your liquid food automated feeding setup. Also curious as to your experience with the Reef Facory equip since I was planning the same.
As for the liquid food, I have drilled a mini fridge placed right behind the wall of the tank in which I have a dosing container. An Ecotech Versa dosing pump is dosing liquid food in to my sump right next to the return pump which delivers food to the tank. I chose this solution to keep the dosing tube as short as possible- and to have it all out of sight!
As for the Reef Factory equipment, it has all been sold as it wasn't quite up to what I wanted sadly.. It has all been replaced with tried and tested Apex equipment.
