This is my new 5.5 DIY nano tank. It was a fun adventure with lots of obstacles to over come. I started with a 5.5 gal tank and a 2.5 gal sump. Stand pipe overflow,jet 900 power head for return,70watt halide and 4 2600mcd blue l.e.d. 12vdc thurmastor fan for light cooling. Tank is up and running as of 3-24-06 P.S. if you ever go to radio shack to find resistor values to step voltage down,just walk away because they dont have a clue. I will try to post pics of my set up.If I fail I will have to have the boss dit:eek2: :eek2:
