The 10 gallon algae tank.
I put 10lbs of live sand, 12lbs of dry rock, an old turbo snail shell, a aqua-clear 70 hob filter with just sponges, and two 2nd gen A029 30 watt LED lights. The lights are on 12 hours a day and set to 100% blue 25% white. The only flow for the tank is the AC 70 as it is pretty strong in the 10 gallon tank. Tank has only been running for almost 4 months. I think it does kind of look cool. I do a 2 gallon water change every 2-3 weeks. It's not on a regular schedule like my other tanks are.
