Ive just set up a 10g with macros as a display, and eventually to harvest for a natural fish food for herbivorous fish and also my urchin. I currently just have a cheap LED strip that clips to the rim, because I had it in the closet and something is better than nothing. You can see it in the first picture. What would you suggest as a lighting option that mounts similar or would be flat mounted on top of the tank? No corals in here, just macros.
