Lighting under canopy

These are the fans I went with:

Decent air flow and you can't hear a thing. I wish I had done this before. It dropped my tank temperature down just right.

This fixture is under 48" long so it fights inside a hood easily.

i use a fixture with my canopy.... 4x250 watt so it gets pretty hot.

i installed 2x 4" computer fans that blow into the canopy. (lowered water temp by 4ºF)
