For lighting I have a 150w sunpod with a 20k ushio (very blue) lamp. For flow I have a mj 900 which replaced the stock ap pump and a aquaclear 20 power head, I'm actually having trouble finding the right amount of flow since the aquaclear is pretty bad. Maybe I'll check out the koralia pumps this week. Finally for extra filtration I have a medium 3g aquafuge packed with rubble rock and cheato.
