Curing Liverocks

Live Rock

Here are helpful steps in fully curing liverocks:

Method 1: Curing Liverocks in a Separate Setup

  1. Place the liverock in any type of plastic container that is suitable in size.

  2. Fill the container covering the liverock completely with saltwater.

  3. Use a heater to keep the water temperature warm. Set to the temperature to near 80 degrees.

  4. Hook up and run a water/powerhead pump in the water so you can create constant water movement for circulation and oxygenation.

  5. Keep it dark in the area during this process to prevent algae attack.

  6. Let it cure.

  7. Curing Live Rock in a Separate Set Up

  8. Perform water changes twice a week and keep measuring and monitoring the ammonia and nitrite levels.

  9. Scrub the liverock during water changes to remove any loose organic matter, debris, or sand and other dead materials.

  10. You will know that your liverock is cured when both ammonia and nitrite levels are zero.

  1. Rinse each piece of liverock in a small bucket of saltwater.

  2. Turn on the heater and water/powerhead pump ONLY.

  3. Let the liverocks cure! DO NOT add live sand or other substrate, livestock, or anything else until the curing process is complete.

  4. Perform 50% water changes weekly while siphoning out any organic matter and loose debris that accumulates at the bottom of the aquarium.

  5. Measure and monitor the ammonia and nitrite levels in the aquarium weekly.

  6. When both ammonia and nitrite levels are zero, perform a 50% water change on the aquarium.

  7. After 24 hours, check the pH of the water and adjust as needed to achieve the desired level of 8.1-8.4.

  8. Once again, you will know that your liverock is cured when both ammonia and nitrite levels are zero.

  9. Once the curing of liverock process is complete, siphon out any debris off the bottom of the tank, and do substantial water change.
