I use glass lids currently as well. My thought is to have only a partial top and no back to prevent trapping heat or stale air. Sounds like I need to keep the glass lids, which is fine.I have a similar setup and use glass lids. Ignoring the debate about whether or not glass lids are a good idea — plenty of threads on that. Besides protecting your fish, it also reduces the humidity and risk of condensation on your lights. My canopy is open on the back side so I have some air circulation that helps with keeping the canopy temp down and also moisture etc.
