I like how it makes the tank look... but I hate it when I'm ready to do water changes. I don't think I would mind as much if I had a 4ft tank... but with a 6ft one, I I usually need help getting it off.
I only have a canopy on my 300 gallon show tank. I built my own so it lifts up to get full access of the tank. The tank is 8 feet long and my canopy is split so there is 4ft sections that can be lifted up separately for easier access. I like it on this tank cause I mount my lights up off the tank.
