Fishkeeping is the practice of keeping fish, marine plants, and other creatures suited to an aquatic environment. More than just a hobby, fishkeeping is a passion for many, and often becomes a family endeavor. Beyond learning the basics of fish care and tank maintenance, fishkeeping provides hobbyists with the opportunity to appreciate the beauty of aquatic life. Increasingly, fishkeepers are seeking out reliable, previously used aquariums and related equipment, such as filters. Saving money is the main reason buyers look for previously used supplies, but convenience is also a factor.

Some enthusiasts might be reluctant to purchase used equipment, thinking that it could be inferior or non-functional. Buyers simply need to know what to look for. Understanding the ins and outs of used aquariums and related equipment is the first step to saving money on what can often be an expensive hobby. This guide discusses such things in depth, and points out things to consider regarding fish and other water animals that are commonly kept in home and office aquariums. It also explains how and where to buy a quality used aquarium at an affordable price.

Benefits of a Used Aquarium

For most buyers, cost is the driving factor behind buying a used aquarium. However, hobbyists looking for a unique aquarium design or older equipment unavailable from retailers often find what they want by searching for used pieces.

Perhaps you are just starting to explore the hobby. Before making a final purchase, would-be aquarium owners should consider the benefits of buying used aquarium and accessories, in order to determine whether the purchase is a good value. Make sure that the tank and supplies are in working order, or if not, attempt to determine an appropriate solution to a broken piece of equipment. Even in situations where a filter or other part calls for minor repair, buying used offers considerable cost savings, especially for high-end equipment.

Used aquariums and equipment do not usually come with user and instruction manuals. However, searching online for the brand and model number (if available) can prove helpful in locating information from others using the same or similar equipment.

Choosing a Quality Used Aquarium

Aside from ensuring that the glass and frame are intact, buyers should learn about any previous issues that could affect tank function. If the tank has not been recently used, ask the seller how long it has been empty. The glass on an aquarium is prone to becoming cracked or weakened when sitting empty for a long time. A recently-used tank is more likely to be free of cracks or leaks. Buyers should understand that sellers might not be aware of small leaks if the tank has not been used or tested recently. Seals may dry and shrink over time, introducing a leak into a previously good tank after long storage. It is possible to test a tank for leaks after purchase, but it carries the risk of water damage if the tank fails. Consider leak testing in a tub if the condition of the tank and its seals are uncertain. Finally, when choosing size and shape of the aquarium, consider whether or not the design will make cleaning and maintenance of the tank difficult.
