These tanks feature beautiful living reefs and corals but are also the most tricky to cultivate. They also require far more equipment than a 'fish only' tank but are well worth the extra effort. Some on the job training is definitely a requirement!
We suggest you start with a fish only tank and once you are comfortable with that, add the coral and reef components.
* 'Fish Only' Tanks
These are tanks that contain fish and live rock or ceramic features instead of natural coral or reef. Here the focus will be on your fish species rather than reef invertebrates.
* Choosing a Tank
No matter which size or style of tank you choose, they will require the same maintenance. Start by determining how much space you want to dedicate to your tank and factor in available space for your outlets since a saltwater aquarium will need a lot of equipment - most of which have cords attached.
Tanks are made of glass or acrylic with the latter being by far more suitable for a saltwater aquarium. This is because the design is far more up to date, with shapes ranging from standard rectangles to cylindrical styles and even round ones. One drawback is that they tend to scratch easily, but marks can be buffed out easily once everything is set up. Interior ones are a different story - to fix these you have to dismantle the tank and have them removed professionally.
* Lighting and Filters
Lighting options are standard but filters range between canister, under-gravel and a special marine filter called a 'wet/dry' filter. This filter is a great choice for the novice aquarist. It is placed outside the tank so cleaning is easier. Before you buy one have an idea of where you are going to place it so that you know how much hose you are going to need. This kind of filter is normally placed at the base of the tank but you can also hide it in nook or cranny. Get extra hose if you think you are going to need it as standard hoses are often too short.
* Water Circulation
Marine tanks are aerated by water turbulence not by the typical aerators found in freshwater tanks. Turbulence is basically used to simulate ocean waves. A good filter will circulate water around your saltwater aquarium via its import and export hoses.
