How to Clean a Used Fish Tank

Who can pass up a cheap tank found at a garage sale, auction or swap meet? With these easy steps you can sanitize a found tank and make it safe for fish again.

The first thing you will need to do, if you are planning on using this tank for fish instead of reptiles or pocket pets, is to be sure that is holds water. In order to do this you will need to:

Now that you have tested your tank for leaks, you will need to sanitize the tank. You can never be sure what lived in the tank, what diseases the occupants may have had, how long it sat in a garage, basement or back porch, or what other things the tank may have been exposed too. The best thing to use for these cases is bleach.

Additional items that might have come with the tank such as filters, heaters, gravel and décor will also need to be cleaned, scrubbed, and thoroughly rinsed using diluted bleach. Filters will need to be taken apart and every piece will need cleansed. Purchasing new filter media is best for this type of situation as used ones cannot be sanitized thoroughly.

So, with a little elbow grease and lots of water you can get use out of those good deals and great finds at yard sales. If it's cheap enough there's no reason to pass it up as sanitizing a good non-leaking tank is fairly quick and easy.
