OK, I impulsively purchased the guts of a T5HO kit, configured with two 48" 54 watt bulbs side-by side at a width of just under 5 inches. However, I find that my two funky junky canopies are both just a tad shy of the width needed to accommodate it.
Checking online, I found instructions for creating a hood from rain gutter. Here is the link- http://saltaquarium.about.com/gi/o....&bts=1&zu=http://www.rcarchive.com/fish/hood/
I wouldn't need something so elaborate, but what about the concept of using rain gutter for a diy hood?
