I would like to have an easy way to raise and lower the entire lighting fixture(s) inside the canopy.
Fixtures mounted to a rack or support that could be positioned closer to or farther from the water surface.
Sort of like a "sliding" rack that would hold the lamps - and be easy to move up and down "inside" the canopy.
Move them up and out of the way when I reach in and work on the tank ~ then when done working inside the tank, move them back down to the normal lighting position height.
That's one thing I will do differently.
Other than that - I'm pretty happy with the outcome
