Quick Answer
Live rock is porous marine rock that supports biological filtration and reef structure. It can bring beneficial organisms, but it must be cured or cycled properly before sensitive livestock are added.
Care and Setup Notes
- Test ammonia and nitrite during curing or cycling.
- Inspect for unwanted hitchhikers before adding to display tanks.
- Use stable rockwork that cannot collapse under burrowing or flow.
What to watch
Use this page as a planning profile, then match the advice to your exact tank size, livestock, temperature, filtration, and water test results. If livestock are already stressed, test ammonia, nitrite, nitrate, pH, and temperature before making big changes.
