So you’re thinking about making the jump to saltwater? Great! The amount of diversity, relationships between species, personalities of fishes, and the COLORS are what this hobby is all about! A reef aquarium is something you’re not likely to become bored with…there’s always something new to see.
Let’s start with dispelling some myths and answering some frequently asked questions:
Aren’t saltwater aquariums a lot of work?
Nope! A typical reef aquarium requires less than an hour per week. A reef aquarium is about creating a complete ecosystem, including organisms that eat algae and recycle wastes. This means no gravel cleaning, and no scrubbing of rocks or ornaments. Most people find that they enjoy working on their reef tank!
Aren’t saltwater aquariums expensive?
They don’t need to be. Cost is directly related to size. Some literature on the hobby suggests buying the biggest aquarium you can afford…this would be a mistake. Many times we see people following this advice, and then not being able to afford the proper equipment and supplies to keep everything healthy. If cost is a concern, start small. It is possible to create a healthy nano reef with a few colorful fish and corals in the 20-30 gallon range for less than $500.
The Basics of Reef Aquaria
One of the cool things about the hobby is that there is always something new to learn, but you don’t need to know a lot to be successful! Jump in and get your feet wet with the basics.
The term may sound strange, but live rock is the most important part or a reef aquarium. Live rock is essentially old coral skeletons that have been colonized by many new organisms that help recycle wastes. Live rock is your biological filter. There is no need for bio-balls, bio-wheels, ceramic media or any other forms of biological filtration. In addition to its essential function as a filter, you will notice many invertebrates grow from live rock over time. Feather-duster worms, crabs, and corals are very common “hitchhikers”.
Water needs to circulate very well in a reef tank. It is essential for oxygenation or gas exchange, filtration, delivering foods to corals and invertebrates, and so much more. One of the best ways to provide water movement is with a propeller pump. These are similar to traditional powerheads, but they move greater volumes of water at slower speeds; similar to ocean currents.
Most corals available for the home aquarium are photosynthetic. This means that they are dependent on the light you provide them with for the majority of their energy, and ultimately their survival. Different species have certain lighting requirements, so your lighting will determine what corals you will be able to grow. For the most cost-effective lighting options, look at T5 high-output fixtures.
Over time, toxic compounds build up in your aquarium water, and desirable compounds are depleted. By changing a portion of your water on a regular basis (about 20% every 2-4 weeks), you can keep the toxic compounds diluted to safe levels, and the desirable compounds available to your reef animals.
Just a small sample of fish and inverts we recommend for beginners. These animals are durable, comfortable in small aquariums, and generally peaceful with other species.
