Tank Lid Frame
So I was dealing with a cat(s) who were constantly drinking from my tank and staring at the fish for far too long. I also needed to raise my light and I wanted storage space outside of the cabinet/easily accessible. We use this AWESOME material at work for a variety of purposes due to its versatility. It's a T-slotted framing material with tons of accessories; hinges, brackets, corner pieces, latches, everything. I originally put 1/4" plexi on the sides and double plexi doors on the front but the doors were a pain in the butt so I only left the plexi on one end where the cats were still sticking their paws.
The brackets on either end are used to hold the light 6" above the tank surface, they can slide front to back. I have swapped a few pairs of legs out trying different heights (ends of the t-slot are pre drilled for 1/4" tap, so very easy to tap new pieces). Plywood top is currently up but typically on top of the frame with the hinges shown in last photo, does not look particularly 'nice' but it was a utilitarian goal. It's light, comes off easily when I need to really get wet (I leave it on for water changes).
I only joined the forum recently but I see similar questions pertaining to elevating lights, keeping pets out so I figured I would share if any were interested. I am re-reading this and see it comes off a bit like an advertisement, was not meant to be. Any one else have creative solutions for over your aquariums?
