Why choose a specific aquarium for seawater?
Differences between freshwater and saltwater aquariums
A marine aquarium isn't just a tank filled with salt water. The biological, technical, and aesthetic requirements are quite different from those of a freshwater aquarium. While a freshwater tank can rely on basic filtration, a marine aquarium requires very precise management of parameters: salinity, calcium, magnesium, KH, pH ... everything must be controlled. And visually, it's on another level: multicolored fish, fluorescent corals, fascinating invertebrates...
Stability of parameters and suitable materials
In seawater, stability is key. Sudden changes in temperature, salinity, or pH can be catastrophic. That's why marine aquariums are designed with robust materials , suitable for long-term use and able to resist salt corrosion. The equipment is calibrated for maximum precision. There's no room for guesswork!
Integrated equipment (technical tank, overflow, lighting)
Modern marine tanks often come with all the equipment built in: technical tank with skimmer, discreet overflow system, high-performance LED lighting , and sometimes even an osmolator to compensate for evaporation. This is what we call "plug & play", perfect for getting started without any hassle.
What type of marine aquarium should I choose?
Reef aquarium (SPS, LPS, soft corals)
The reef aquarium is a living gem. It's home to a mix of fish, soft corals, long-polyp stony corals (LPS), and small-polyp stony corals (SPS). It's the kind of tank that makes you dream : flashy colors, constant movement, and teeming with life. But it requires discipline, especially if you're aiming for the more demanding SPS corals.
Bac fish only
Less restrictive than reef, fish only (or FO) is dedicated solely to fish. No need to manage the specific needs of corals , but you will still need good filtration, well-mixed water and stable parameters. Perfect for admiring beautiful marine fish without complicating your life.
Nano aquariums for seawater
Small but strong, nano marine tanks (30 to 100 L) are ultra trendy. Their small footprint makes them accessible to everyone, even in apartments. With good lighting, a suitable skimmer and regular maintenance, you can keep a few soft corals and small colorful fish . Ideal for starting or completing a collection!
Getting started with a marine aquarium
Recommended volume for a first marine tank
To begin, aim for a tank between 100 and 250 liters. Any smaller, and the parameters will change too quickly. A good size provides a safety margin and allows for more biodiversity (corals, scavengers, fish). It's also easier to install all the necessary equipment.
The Importance of the Nitrogen Cycle and the Skimmer
No life without a cycle! You have to let the tank "mature" for several weeks, so that the bacteria can colonize the rocks and sand. This is what allows the ammonia to be transformed into nitrates. And to keep the water clean: the skimmer is essential . It eliminates dissolved proteins before they pollute the water.
Budget, maintenance and tips for beginners
A marine aquarium costs more to set up, but with the right choices, you can stay within a controlled budget. Complete kits are perfect for getting started. Set aside a little time each week for maintenance (water tests, partial changes, skimmer cleaning). And above all, take it one step at a time : live rock, scavengers, soft corals, then the fish, slowly.
FAQ
What size for a beginner reef aquarium?
A reef tank between 150 and 250 liters is ideal. Large enough to stabilize the parameters, yet compact enough to remain manageable. You'll be able to house a nice diversity of soft corals, a few LPS, and a small group of fish.
Are saltwater aquariums more difficult to manage?
They require more attention, yes, but nothing insurmountable. With the right tools, a little reading, and patience, it's a pleasure . The important thing is to start off well, not to skip steps, and to get support if necessary.
What equipment is essential with a marine tank?
Here's the basics: a suitable tank, good LED lighting, a high-performance skimmer, a heater , an osmolator (or failing that, monitor evaporation), efficient mixing , and tests to monitor salinity, KH, calcium, and nitrates . And of course, quality osmosis water for your water changes.
