Instructions
Ask questions before buying a used fish tank. Depending on what you'll use the fish tank for, it's important to know how old the tank is, if it's been repaired, what animals have lived in the tank and if a lot of fish died in the tank from disease.
Buy a used fish tank that fits on a premade aquarium stand. Custom made fish tanks, while different, are harder to find stands for and may look awkward in your home.
Check the glue or silicone used on the tank glass, and make sure it's still tight. If the glue is loose, you will need to reseal the tank, let it sit and water test it before you can buy fish.
Inspect the tank for tiny chips in the glass. Stay away from tanks with large cracks or splits, because the time and money you spend fixing the tank is better spent shopping for a new tank. If the used tank has a small chip, simply sand it down so it doesn't leak in the future.
Try and get a used fish tank with equipment. Many sellers are getting rid of filters, gravel, decorations, lights and food along with the tank. If you don't see any equipment with the tank, make sure to ask and you can usually get a good deal on used fish tank equipment.
Clean the tank when you get it home and water test it. Fill the tank up with water and let it sit for a few days. If no water leaks out, prepare your tank for fish and set it up.
How to Buy a Used Fish Tank
A used fish tank can help you save money if you're just starting out as a new fish hobbiest. It's also a good idea if you're buying the tank for animals other than fish, such as a turtle or a snake. Shopping for a used fish tank is easy, with only a few details to worry about before buying.
