As the school year began, I emptied my school fish tank so that it could be moved from home to my office. In the process of carrying it to my car, the glass cracked on the side. I had planned on throwing the tank away. Then I came up with the idea of joining the 20 gallon and 29 gallon tanks into one long tank.
The plan took quite a bit of research but came together quickly. I removed the silicone caulking on one end of each tank. Then I placed them on their side and shattered the glass with a hammer and screw driver. Once I had cut away all of the broken glass and silicone, I washed the tanks. Because the tanks are different sizes, I built a base for the 20 gallon tank which makes it level with the 29 gallon tank.
I bought an inexpensive piece of plexiglass from home depot and used a heat gun to bend it. This bridges the gap between the two tanks height. If I were to do it again, I would not have made it visible from the outside.
Lastly, I used one tube of clear aquarium silicone to bind it all together. Once the silicone had dried for 2 days, added the sand/coconut fiber substrate, decorations, water, food, and ceramic heat lamp. I am considering painting the back of the glass like my office tank. I also want to add some vegetation.
Here is the finished product (without the heat lamp):
