Reef Tank Buyer’s Guide

What is a reef tank?

A “reef tank” is an aquarium that holds more than just fish. It looks like a natural reef, just like you’d find at the bottom of the ocean complete with coral and other marine invertebrates. Of course, the fish are still a hugely important part as they help keep the reef alive and healthy!

What is the difference between a reef tank and other fish tanks?

The main difference is that reef tanks have coral and other living aquatic fauna in addition to fish. It’s a mini underwater eco-system that is very beautiful but takes some careful consideration to not only put together and a little more work to maintain than your traditional fish tank. Reef tanks require a stronger, more turbulent flow of water, a highly maintained water chemistry and lighting that is carefully chosen in the reflection of the wildlife inside the water. Often, it means more intense lighting.

What are all the parts that are needed to put together a reef aquarium?

To put together a reef tank, you’re going to need some more specific parts than your traditional fish tank because of what is required for all the aquatic life living inside. First, you’ll need a tank that is ready for a filtration system and has some sort of hole drilled into so water can drain out. It will also need a “sump” which is an accessory tank that houses all the mechanical equipment. You’ll also want a refugium, which is a tank where tiny algae and flora and fauna are grown. This is very beneficial to the ecosystem you have growing in your reef tank! You’ll also need a high-powered filter that will manage the movement of the water in the tank and depending on the kind of coral, fish and other sea life you are growing, you’ll want a specialized light as well. One more thing that is not necessary, but many people choose to purchase, is a stand. Your tank will be like a work of art you will want it on display and a stand will help with that, and help support it!

What are the best kinds of fish for a reef aquarium?

You’ll want a fish that does not feed on coral, is not too aggressive, and does not require a special diet. The most popular fish for reef tank aquariums are Clownfish, Royal Gamma, Firefish, Midas Blenny, Dottyback, Tangs, Butterflyfish, Orchid Dottyback, and Six-Line Wrasse.

What are the best coral and marine life for my reef tank?

There are some really beautiful corals out there, but make sure that you’re buying a coral that will work well with the environment you’re creating as a whole. We recommend the flowerpot coral, brain coral, candycane coral, button polyp, daisy coral, gonapora, candycane coral and frogspawn coral. Plus, make sure you get some cleaner shrimp as well-they will eat organic material that is flowing around in your tank.

Is there a specific temperature I should keep my reef tank at?

Yes! Think of your reef tank as a small chunk of the tropical ocean within your home. That being said, the temperature that best promotes the growth of coral, fish and other invertebrates is between 25 to 28 degrees Celsius (that’s about 75 to 82 degrees Fahrenheit). The temperature should be kept very consistent to ensure your organisms stay alive. This is part of the reason why where you choose to place your reef tank is so important. For example, if you choose to put it near a window, on a hot sunny day, the temperature in the tank could rise quite substantially and then lower when the sun goes down. One way to prevent that is to install a heater or chiller on the tank. Heaters are not very expensive, in fact, you can purchase one at any local pet store. However, chillers are pretty expensive, and you have to buy them at a more specialized store or online. The good news is there is a cheaper solution. You can often run the air conditioning in your home and then use a surface fan, thereby taking the place of the chiller.

Can I only have a saltwater reef tank? Is there such a thing as a freshwater reef tank?

In short, a true “reef” tank is created with fish, coral and flora and fauna that would be found in a coral reef, which occurs naturally in the ocean, which is saltwater. Many people have tried to recreate a reef tank with freshwater fish, plants, etc and have found some success, but it is ultimately a different setup and maintenance program than what you would follow for a saltwater reef aquarium.

Are there any safety concerns associated with a reef tank?

Yes, there are. Anytime you put water near electricity, especially saltwater, there is a risk for harm to not only humans but also the fish and wildlife inside of the tank, which is why it is so important to be careful when setting up and maintaining your tank. Saltwater is electrically conductive by itself but with reef tanks, there are multiple electrical appliances kept in close proximity to the tank. Make sure that you are using all the equipment as required by the manufacturer’s instructions. Never exceed the circuit limits of your outlets, place electrical equipment above water when you can and make sure all appliances are first plugged into a ground fault circuit interrupter outlet or power strip. These are inexpensive and are available at home improvement stores. To be extra sure of safety, you can also purchase a monitoring system with sensors that let you know if the power goes out at your home or if water spills out of the tank, etc.

How much is this all going to cost me?

On average, reef tanks are far more expensive than their less complicated or freshwater counterparts. A larger tank, between 50-90 gallons is going to cost about $2,000 to set up if you’re doing it right and will cost about $20 per month for heating, lighting and filtering the tank. Plus the additional costs for chemically testing and treating the water, and buying the fish food of your choice. However, you can set up a tank that is 10 gallons for a little over $150 and it will cost you about $4 a month in total for filtration, heating, and lighting with the additional cost of food and water treatments.
