Just my .02
I have a 150 it came with a canopy
the canopy is extremely heavy to lift up and down even though it's hinged
I installed 3 lift up doors acrossed the front thinking that would solve a lot of
up and down of the main canopy, but it hasn't. The tank is 29" deep and we have
to use a grabber to move things around so you MUST raise the main canopy to do that.
also be certain to vent for your lights, not only above the lights but even fans on the
side to cool them. I am running for 4 AI's and AI thinks I am having cooling issues.
also most LED's are designed for 12" min above the water, with a canopy you may only
get 8 or 10 inches.
so my synopsis, while it looks nice, not certain of the practicality of a canopy. perhaps
once everything is in the tank and you're not like us constantly adding and moving things
around our canopy will be fine.
Right now I have been looking for ways to automate the raising and lowering of the canopy.
linear actuators on ebay are a possibilty LOL
Good luck and let me know if you have any questions
