How Much Does Coral Keeping Cost? Monthly Running Costs Explained

Coral keeping is one of the most labor-intensive and costly hobbies in the marine aquarium world. Maintaining a beautiful reef tank requires expenses across many areas, including lighting, water quality management, and additives. This article breaks down both the initial setup costs and monthly running costs of coral keeping with specific price ranges.

Initial Setup Cost Estimates

• Aquarium (60cm): 10,000-30,000 yen (dedicated all-in-one tanks are pricier but easier to set up)
• Lighting (LED): 20,000-50,000 yen (high-quality LEDs essential for coral photosynthesis are the most important equipment)
• Protein skimmer: 15,000-30,000 yen (essential for organic waste removal)
• Live rock: 5,000-15,000 yen (for beneficial bacteria colonization and aquascaping)
• Synthetic sea salt and hydrometer: 3,000-5,000 yen (needed in bulk during initial setup)
• Circulation pump and wave maker: 5,000-20,000 yen (water flow is key to coral growth)
• Other (heater, chiller, calcium reactor): 10,000-40,000 yen

The total initial setup cost is estimated at 70,000-200,000 yen. The grade of equipment needed varies depending on the type of coral (LPS, SPS, or soft coral).

Monthly Running Costs

• Electricity: 3,000-8,000 yen (the largest expense, covering lighting, pumps, chiller, and heater)
• Synthetic sea salt: 1,500-3,000 yen (needed for regular water changes; premium brands cost more)
• Additives (calcium, magnesium, alkalinity): 1,000-3,000 yen (essential for SPS keeping)
• Filter consumables and activated carbon: 500-1,500 yen

The estimated monthly maintenance cost totals 6,000-20,000 yen.

Tips for Saving Money

• Use a timer for lighting: Optimize electricity costs with 8-10 hours of illumination per day
• DIY additives (two-part dosing): Replenish major elements at a lower cost than commercial products
• Buy sea salt in bulk or refill packs: Choose larger quantities to reduce the unit price
• Start with soft corals: They require fewer additives and lower light intensity, keeping both initial and ongoing costs down
