What You Should Know Before Starting a Coral Tank
A coral tank (reef tank) is one of the most rewarding aspects of aquarium keeping, allowing you to recreate a particularly vibrant ecosystem from the ocean in your home. However, unlike freshwater fish keeping, it requires a high level of knowledge and preparation in water quality management and equipment selection.

Most failures stem from insufficient preparation. By gathering all necessary equipment before setting up the tank, completing the cycling process (establishing beneficial bacteria), and only then introducing corals—following these basic steps alone will greatly increase your success rate. This article provides a systematic explanation of everything from equipment selection to tank layout design for those attempting a coral tank for the first time.

Necessary Equipment and Selection Tips
Maintaining a coral tank requires more equipment than a typical saltwater fish tank. Understanding the role of each component and selecting items appropriate for your tank size is essential.
Tank and Filter
For coral keeping, a tank of 60cm or larger is recommended. The greater the water volume, the more stable the water quality becomes, and the risk of rapid parameter fluctuations decreases. While an overflow system using a sump (external filter reservoir) is ideal, an external filter can also work. It is important to ensure sufficient biological filtration capacity.
Protein Skimmer
A protein skimmer is a device that removes organic matter (proteins) from seawater by skimming foam from the surface. By promptly removing mucus secreted by corals and leftover food, it prevents the accumulation of nitrate. Choosing a model with processing capacity 1.5 to 2 times your tank volume provides peace of mind.
Lighting
The zooxanthellae (symbiotic algae) in corals perform photosynthesis, serving as the coral's energy source. Therefore, lighting is one of the most important pieces of equipment in coral keeping.
SPS (Acropora, etc.): Requires high PAR values (200–400 or higher). High-output LED or T5 fluorescent lights are essential.
LPS (Fungia, etc.): Can thrive with moderate PAR values (75–150).
Soft Corals: Can grow with relatively low PAR values, making them beginner-friendly.
Time management is important with lighting—aim for approximately 8–10 hours of operation per day. Use a timer-equipped controller.
Circulation Pump
Corals obtain oxygen and nutrients through water flow. Weak currents can cause tissue necrosis, so creating complex water flow from multiple directions is essential. Install two or more wave pumps with random mode to eliminate dead spots (areas where water stagnates). However, constantly directing strong flow directly at specific corals can damage them, so angle adjustment is necessary.
Temperature Control and Water Quality Testing Equipment
Heater and Cooler: Maintain water temperature around 26°C. A cooler is essential during summer.
Hydrometer and Refractometer: Precisely manage specific gravity at 1.024–1.026 (ideal is 1.025).
Test Kits and Measurement Tools: In addition to ammonia, nitrite, and nitrate, regularly measure calcium (Ca), alkalinity (KH), and magnesium (Mg), which are essential for corals.

How to Cycle Your Tank (Startup Process)
Before introducing corals, you must establish beneficial bacteria in your tank that perform biological filtration. Skipping the cycling process will cause ammonia and nitrite to spike, killing your corals.
Set up a clean tank with synthetic seawater, substrate, and live rock, then run all equipment.
Add an ammonia source (pure ammonia or a small amount of fish food) to feed the bacteria.
Test water quality daily and confirm the ammonia → nitrite → nitrate progression.
The cycle is complete when both ammonia and nitrite are no longer detectable.
This typically takes 4–8 weeks, though bacterial additives (such as biostarters) may shorten the duration. Taking your time to properly complete the cycle is the foundation for long-term tank maintenance.

Selection and Placement of Live Rock
Live rock (porous stone) is important material that serves as a habitat for beneficial bacteria while creating the aquascape.
Amount: Approximately 10–15% of your tank volume. Excess rock reduces water flow.
Shape Selection: Arranging rock in arch or tunnel shapes improves water circulation.
Coral Placement: Use frags (small fragments) and frag racks, and minimize direct placement of corals on live rock. Direct placement makes relocation difficult and can cause problems as corals grow.
Live rock contributes significantly to water purification as a habitat for nitrifying and denitrifying bacteria, not just for aesthetics. Selecting high-quality cured live rock will also speed up the cycling process.

Basics and Considerations for Layout Design
Coral layout design should consider not only visual aesthetics but also the differences in light requirements, water flow preferences, and toxicity levels of different species.
Basic Zone Layout
Position
Recommended Coral Types
Reason
Rear/Top (High Light, Strong Flow)
SPS (Acropora, common types, etc.)
Prefer strong light and flow
Middle (Moderate Light, Flow)
LPS (Fungia, octopus arm corals, etc.)
Prefer moderate conditions
Front/Bottom (Low to Moderate Light)
Soft Corals (Zoanthids, disc corals, etc.)
Shade tolerant; beginner-friendly
Pay Attention to Contact and Growth Space
Some corals have sweeper tentacles that attack neighboring corals or release toxins. Always leave at least 10–15cm spacing between corals and plan for future growth. Placing LPS and SPS close together can result in SPS being damaged by LPS sweeper tentacles.

Br-Choku's Safe and Secure System
Once your coral tank is set up and cycled, it's time to introduce corals. For your first corals, soft corals are recommended as they're relatively hardy and easy to care for.
In Br-Choku's Coral category, you can find corals of all sizes, from frags (small fragments) to large colonies directly listed by breeders. Because it's a direct-sales format without going through retail shops, a major advantage is that you can directly confirm the condition of specimens and rearing environment with breeders.
Seller Inquiry Feature: Ask about water parameters and care history beforehand.
Abundant Frag Availability: Try multiple species while keeping costs down.
Safe Payment and Transaction Management: The platform mediates transactions for peace of mind.
Building connections with reliable breeders while perfecting your tank is also one of the joys of coral keeping. Please find the perfect coral for your tank on Br-Choku.
