When looking at large aquariums, it’s amazing when you realize that all that water is held back by a few thin beads of silicone. While it is common practice to use the material to stick sheets of glass together, the seams occasionally burst open, draining the water from the aquarium. Because of this, it is extremely important to inspect the seams of a tank thoroughly before purchasing it. If the seams have bubbles in them, or the silicone is not uniform and going completely through the seam, then you want to save yourself the future headaches and walk away. Get an aquarium with good, quality seams that aren’t damaged in any way. And when you start setting up the aquarium, do an extended leak test. After all, it would be a shame to set up a tank and get it full of livestock only to find a leak.
