hmm hex tanks are hard to light. Maybe you can get an ahsupply 2 x 13 watt kit ? The stock hood reflectors you have suck so you would possibly get half the wattage . there are lots of guests viewing the forum so don't be alarmed when theres 12 views and no replies. how tall/wide is the tank ? Also you could probaly build a hood for the light and ditch the plastic since it will melt with the lights on it.
