I've now read this whole thread. I've enjoyed it very much. There are so many great ideas. Thanks for sharing the technical details of your 280g(#133). I like what you've done with the lighting. I'm planning a system of two aquariums, they will be filtered internally and topped off with RO. Minimizing water consumption is also going to be important for my household. So, I'm thinking to run a portion of water from the filter through an algae scrubber and populate it with daphnia. I hope to use about 60 gallons water per week (A 15% water change - which will be recycled into laundry use.)
