DIY Nano MH Canopy
 

does anyone have any good sites that show how to make a good MH canopy for smaller tanks? have any of you out here made them yourself and if so, could i see some pics? Ive got a few ideas about how im going to build mine, but advice and tips are always appreciated!

Im putting a 175W SE MH and 24" pc over a 20G long(30").

Have you decided how you want the canopy to open? Have you considered hanging a canopy to keep the heat down?

MH hood
 

Before you spend a lot of time figuring how you will build it, have you figured out how you will keep it cool? I have a 16 gal with a 5.5 (about the same volume as you) sump and a 175 MH SE in a pendent 8 inches above the water and I still had a little heat issue. I had to buy a chiller :( Can you use a pendent, or does it HAVE to be a hood?
