Your step-by-step guide to building a thriving Reef Tank

Starting a reef tank is a rewarding endeavour that offers a unique and stunning display of marine life in your home. While it may seem complicated, following this step-by-step guide will simplify the process, ensuring your reef tank gets off to a strong start. Whether you’re just starting or expanding your setup, this guide will provide in-depth advice on every essential aspect of setting up a thriving reef.

Step 1: Choosing the Right Tank

Your tank choice is critical and will set the foundation for your entire reefing experience. The size and material of your tank directly impact its stability, ease of maintenance, and the types of livestock you can support.

• Beginners: A tank between 20 and 50 litres is a manageable size. These smaller tanks are ideal for getting started, but they do require frequent monitoring as small volumes of water can experience rapid parameter swings.
• Intermediate and Advanced: If you're looking for a more advanced tank, consider upgrading to a larger system. Brands like Waterbox and Cade offer a wide variety of tanks, ranging from compact desktop options to expansive 8-foot tanks. Larger tanks provide more stability due to their larger water volume, which means they can handle fluctuations in water chemistry better than smaller tanks.

Pro Tip: Consider a tank with a built-in sump or the option to add one. Sumps offer additional water volume, hidden filtration, and make maintenance more streamlined.

Step 2: Setting Up Your Equipment

Once you’ve selected your tank, it’s time to gather essential equipment. Each piece of equipment plays a specific role in ensuring your reef system thrives.

• Filtration System: One of the most critical components of any reef tank. Choose a high-quality filtration system like a protein skimmer to remove organic waste before it turns into harmful toxins. We recommend Bubble Magus skimmers as a starting point for their reliability and effectiveness and price point.
• Lighting: Proper lighting is crucial for coral health and growth. Corals rely on light to photosynthesize, so choose an LED light that mimics natural sunlight. Reef Factory lights allow precise control of light spectrum and intensity, ensuring your corals get what they need.
• Heaters & Thermometers: Maintaining a stable temperature between 24°C and 26°C is essential. Invest in a reliable heater with a backup thermometer to ensure accurate readings.
• Powerheads & Wave Makers: Water flow is essential to mimic the natural environment of the reef. Powerheads and wave makers prevent detritus from settling and ensure water movement throughout the tank, helping corals thrive.

Step 3: Mixing Your Saltwater

Achieving the correct salinity and water quality is crucial for a successful reef tank. If you're using tap water, be sure to filter it using an RO/DI (Reverse Osmosis/Deionization) system to eliminate contaminants. You’ll also need a high-quality salt mix designed specifically for reef aquariums.

• Salinity Levels: Aim for a specific gravity between 1.024 and 1.026, replicating the natural salinity of ocean water. Use a refractometer to ensure accurate readings.
• Pre-Mixed Saltwater: If you want to save time, The Coral Shop offers pre-mixed saltwater, ensuring consistency in salinity without the hassle of mixing.

After mixing, use a Spin Touch system (available at our store) to test your water before adding any livestock, ensuring the salinity, pH, and alkalinity levels are within acceptable ranges.

Step 4: Cycling Your Tank

Cycling your tank is a process that establishes the necessary bacterial colonies to break down waste and convert harmful ammonia into nitrite, then nitrate. This is a crucial step, as it ensures your tank can support marine life without exposing them to toxic chemicals.

• The Nitrogen Cycle: Add a source of ammonia (such as fish food or a specific cycling product) to begin the nitrogen cycle. Over 2-6 weeks, beneficial bacteria will develop to convert harmful ammonia into nitrite, then to less harmful nitrate.
• Monitoring the Cycle: Use Salifert Test Kits to regularly check ammonia, nitrite, and nitrate levels. You’ll know the cycle is complete when ammonia and nitrite are at zero, and nitrate is below 20 ppm.
• Speeding up the Process: Products like Brightwell Aquatics Micro Bacter Start XLM can introduce live bacteria into your tank to help speed up the cycling process.

Important: Never introduce corals or fish until your tank has fully cycled, as premature additions could expose them to toxic levels of ammonia and nitrite.

Step 5: Building Your Aquascape

Aqua scaping is both a functional and aesthetic part of setting up your reef tank. Creating a dynamic aquascape provides hiding spots for fish and room for corals to grow, all while ensuring proper water flow.

• Live Rock vs. Dry Rock:
• Live Rock: Introduces beneficial bacteria and microfauna that aid in cycling your tank faster.
• Dry Rock: A reef-safe option that avoids introducing unwanted hitchhikers and allows you to design your layout more precisely.

Secure rock structures with reef-safe epoxy or superglue to ensure stability. This is important because shifting rocks can lead to broken corals or damage to your tank.

Tip: Build your aquascape with water flow in mind. Avoid dead spots where detritus can accumulate by placing powerheads strategically to ensure even water circulation.

Step 6: Selecting Your First Corals

Now that your tank is set up and cycled, it’s time to select your first corals. Choose hardy, beginner-friendly corals that are more forgiving to fluctuations in water conditions.

• Zoanthids: Colourful and easy to care for, they’re a favourite among reefers. They grow quickly and adapt well to various lighting conditions.
• Mushroom Corals: These low-maintenance corals can thrive in low to moderate lighting and are perfect for smaller tanks or areas with less intense flow.
• Soft Corals: Leathers or green star polyps are beginner-friendly choices that grow quickly and require minimal care, making them excellent first additions to your reef.

Pro Tip: Place your corals in lower-flow areas initially to allow them to acclimate before moving them to more dynamic spots in your tank.

Step 7: Adding Fish to Your Reef

Once your corals are established, you can start adding fish. Introducing fish slowly will ensure your biological filtration can handle the increased bio-load.

• Beginner Fish:
• Clownfish: Hardy and iconic, clownfish are often the first choice for new reefers.
• Gobies: Small, peaceful fish that thrive in smaller reef setups.
• Blennies: These unique, algae-eating fish help keep your tank clean while adding character.

Be sure to introduce fish one or two at a time and monitor their behaviour to ensure they are acclimating well to the environment.

Tip: Always quarantine new fish for at least two weeks to avoid introducing parasites or diseases into your display tank.

Step 8: Maintaining Your Reef Tank

Regular maintenance is the key to a long-lasting, healthy reef tank. Follow these essential steps to keep your system in top shape:

• Weekly Water Changes: Perform 10-20% water changes to remove excess nutrients and replenish trace elements that your corals use up.
• Test Water Parameters: Use Salifert Test Kits to regularly check your tank’s pH, salinity, nitrate, phosphate, and alkalinity levels.
• Clean Equipment: Regularly clean your protein skimmer, powerheads, and other equipment to ensure they are functioning properly.

For those looking to automate their maintenance routine, Reef Factory systems can automate dosing, lighting schedules, and water quality monitoring, allowing you to focus on enjoying your reef.
