Coral Quarantine Guide | Safe Procedures for New Introductions
When you get new corals, I understand the desire to add them to your main tank right away. However, resisting this impulse and performing a "quarantine" is the most critical step in maintaining a healthy reef tank long-term.
Quarantine is a preventive measure in which newly introduced corals are kept in a separate isolation tank for a period of time to prevent pests, pathogens, and parasites from being introduced to your main tank. Skipping it even once can lead to infestations of flatworms or red bugs that collapse the entire tank ecosystem. After reading this article, you should have a clear understanding of the importance of quarantine and the specific methods involved.
Quarantine Tank Setup and Required Equipment
Set up the quarantine tank as completely separate equipment from your main tank. You won't need many pieces of equipment, and they can be assembled relatively inexpensively.
Tank size: A small 20–40L tank is recommended for easy handling and simpler medication concentration management. Since corals don't move, you don't need much space, but it's convenient to have enough room to quarantine multiple specimens simultaneously.
Lighting: A lower-output LED than in your main tank is sufficient. Corals under quarantine are somewhat stressed, and strong lighting can actually cause damage. The basic principle is to gradually increase light intensity over time.
Water flow: A single small submersible pump is enough. Stagnant water causes coral slime to accumulate and deteriorate, so always maintain gentle water movement.
Temperature control: Keep the temperature the same as your main tank (25–26°C). Have a small heater and digital thermometer on hand. Temperature differences place additional stress on corals during transfer.
Water quality: Ideally, use established water from your main tank rather than fresh new water. By matching specific gravity (~1.025), pH (8.1–8.3), and alkalinity, you minimize the adaptation stress on corals.
