Introduction | What to Know Before Bringing Home New Corals
When you acquire new corals, the urge to put them directly into your aquarium is understandable. However, introducing them without proper preparation exposes your entire existing aquarium to risk. It's not uncommon for pests to lurk on the coral's surface, in the gaps of live rock, and in the water of transport bags—creatures so small they're difficult to spot with the naked eye.
Common pests include translucent flatworms, tiny red dots known as red bugs, and nudibranchs that feed on coral tissue. Even a single pest attaching itself to existing corals can spread infection throughout your tank, potentially damaging all your corals.
Two essential procedures to minimize these risks are "dipping (medicinal bath)" and "acclimation." While they require some effort, performing these steps carefully ensures a healthy introduction and contributes to the long-term maintenance of your reef tank.
What Is Dipping? | Choosing the Right Medication
Dipping is a process in which corals are briefly immersed in a specialized medication solution to remove surface pests and parasites. The most common commercial dipping solutions include:
- Coral RX: The most widely used dipping agent. It's effective against a broad range of pests including flatworms, red bugs, and nudibranchs, making it beginner-friendly.
- Bayer: Originally developed from agricultural pesticide components, it's particularly effective against flatworms. Since dosage adjustment is necessary, it's better suited for more experienced aquarists.
- Revive Coral Cleaner: A relatively mild formulation that's easy to use on delicate corals.
When choosing a medication, consider the types of pests you're targeting and the species of coral you're introducing. Use gentler products for sensitive species like SPS, and switch to stronger solutions like Bayer when pest infestation is suspected.
