5/11: Bought 3 pots of HC Cuba and divided it up and planted. I am going to go with DSM on this tank.
Light is a single 23W 5500K CFL vertical in a 6.5" IKEA lamp, mounted 14" above substrate. 12 hours burn period on a timer. Too much light, too little? I might go with 2 lights later for a more even spread.
Total cost thus far: $61
