MickS77 Posted January 8, 2021 Share Posted January 8, 2021 This is a brief overview of the tools and techniques I've used to build three aquarium canopies this way. My intent with building a canopy is to block the glare from the lights and light spillage into the rooms. I also want enough room inside the canopy to be able to reach in the tanks if I have to without having to remove it. I use 1/2" Sande Plywood for a nice paintable surface while still being lightweight enough to lift on and off. It does require a moderate set of wood working tools and the knowledge to use them. I used the following. Tablesaw and Dado blade set Miter saw Kreg Pocket Screw Jig Drill To start I take measurements of the aquarium frame that'll determine the inside dimensions of the canopy. This is a 48x18, 90 gallon tank. I like the canopy to cover the black plastic frame of the tank. You could extend this lower to cover the water line as well. Once I determined the dimensions I use a tablesaw to rip the plywood to length. I like to start by assembling the front of the canopy where the doors are. I found a 10" tall opening was good for fitting my arm in and out of easily. I assembly the entire canopy using pocket screws drilled with a jig. I then make the sides of the canopy. I use a stack of dado blades to cut a groove in the sides. The groove will hold a strip of wood the will sit on top of the aquarium frame, holding it up in place. I screw the sides into the inside of the canopy front so that the cut edge will be hidden from the front view. I attach the back of the canopy the same way as the sides. I screwed the back panel on within the inside of the canopy so the side hides the edge of the back panel. At this time I glue in a strip of wood cut to a specific width to fit fully into the dado and extend out enough to sit on the rim of the aquarium frame. Take care not to make it too wide so you can get the glass lids on and off. Test fit confirms all is good to proceed. After that the top is the last major piece followed by fitting the doors. I found a 1/2" overlap on the doors is good. These are the hinges I use. Finally I attach some simple trim around the top to hide the edge of the top panel to give it a nice look. I painted with a semi-gloss black paint. I don't have any filter equipment running over the rim of this tank but you could trim out to allow access for filer tubes, HOBS, etc. I do plan on trimming a small access cutout on the back, for wires and airline, once I determine the light orientation. I'm no expert woodworker but I found this easy to make. May it serve as inspiration for you to design and build your own aquarium canopy instead of buying one. 8 1 Link to comment Share on other sites More sharing options...
StevesFishTanks Posted January 9, 2021 Share Posted January 9, 2021 Cool project and write up. Thanks for taking time to post. What table saw do you use? My dewalt can't take a dado so I have to do multiple passes or use a router. Link to comment Share on other sites More sharing options...

Andy's Fish Den Posted January 11, 2021 Share Posted January 11, 2021 Nice write up and canopy build. It's simple but it still looks nice, and with some trim can be made as elegant as you would want. Link to comment Share on other sites More sharing options...
Bill Smith Posted January 14, 2021 Share Posted January 14, 2021 Did you have to cut holes or notches out of the back for cables and things that hang off the back? Link to comment Share on other sites More sharing options...

I will once I settle on cord/airline locations. I'll use a hole saw then cut up from the bottom with a jigsaw, then touch up the paint. 1 Link to comment Share on other sites More sharing options...
Bill Smith Posted January 14, 2021 Share Posted January 14, 2021 Ah, thanks. I have a couple canopies that I made, that I'm not happy with the workmanship. I will have to try yours, but without the dado work (I have no table saw). I think I can do the side supports differently. Really nice work, thanks for the inspiration! 1 Link to comment Share on other sites More sharing options...

I only cut one notch for the Stringray power cords and an airline if I want to use one. I used a 1/2" spade bit and an oscillating tool with a wood blade to cut out the notch. 2 Link to comment Share on other sites More sharing options...
Dee of CNY Posted January 21, 2021 Share Posted January 21, 2021 Looks awesome. My husband built a cabinet over my 40 gal. aquarium & placed it in a wall. Black mold developed on the wood. I'm going to repaint with mildew resistant paint used for wet areas. 1 Link to comment Share on other sites More sharing options...
