Why Coral Dipping Matters
Dipping can remove or stress hitchhiking pests on frags and colonies before they enter your display.
It also forces a slow inspection moment—mouths, base, slime coat, and obvious hitchhikers—before placement.
What Dipping Can and Cannot Do
Dipping may reduce flatworms, nudibranchs, and some external pests when products are used correctly.
It does not replace quarantine, does not fix bacterial infections inside tissue, and does not eliminate all eggs or hidden pests.
Visual Inspection First
Inspect the frag plug, rock base, and polyp mouths under good light. Note unusual spots, receding tissue, or visible hitchhikers.
If tissue looks severely damaged or unusual, pause introduction and research before dipping alone.
Separate Container Setup
Use a clean dipping container dedicated to coral work—not food prep containers from the kitchen.
Match temperature and salinity to the destination tank within a normal acclimation range.
Dipping Procedure
Follow the dip product label exactly: concentration, time, and rinse steps vary by formulation.
Gently agitate water during the dip so solution contacts hidden surfaces on the plug and base.
Rinsing
Rinse in clean tank water or a separate rinse container per label instructions before introduction.
Do not skip rinse steps to save time—residual dip can stress corals and tank mates.
Observation After Dipping
Watch polyp extension and slime response over 24–48 hours. Some corals close briefly—that can be normal.
If tissue recedes rapidly or pests reappear, isolate the coral and review pest prevention practices.
Common mistakes
- Skipping temperature and salinity matching
- Leaving corals in dip longer than the label recommends
- Assuming one dip eliminates all future pest risk
- Introducing into the display without inspecting the plug base
