DIY Reflector for Metal Halide

[wildcats]

Hello everyone!
I'm about to install a 250w metal halide in my 65g tank but i need to make some kind of a reflector. Does anyone have any links, pics, or ideas on what I can use??

Go to <a href="http://www.aquaticlight.com./" target="_blank">http://www.aquaticlight.com./</A> and look at thier reflectors.They are pretty cheap,so you may just want to order one...But a thin sheet of polished aluminum is best.Then bend it in an arch around the bulb.The reflector should be spaced away from the hood at the mounting points to allow air to circulate behind it.This will keep your canopy from getting too hot...
