Yes, you can dip live rock.
Dipping live rock is a common practice used to remove unwanted pests and organisms before adding the rock to an aquarium. Based on the severity of potential infestations, there are different dipping methods you can use.
Methods for Dipping Live Rock
The choice of dipping solution often depends on the specific issues you are trying to address on the live rock.
-
Hypersalinity Dip:
- This is the most common method.
- It is generally sufficient for most live rock when you want to remove minor pests or prepare the rock for your tank.
- This method involves using water with a higher salinity than standard aquarium water. The duration and specific gravity for a hypersalinity dip can vary depending on the source consulted, but the principle is to stress unwanted organisms without severely harming the rock structure or beneficial life as much as a freshwater dip might.
-
Freshwater Dip:
- This method is an option for live rock infested with lots of unwanted pests.
- A freshwater dip is a more aggressive approach.
- It generally lasts 2-5 minutes long.
- Use a freshwater dip only in extreme cases because good hitchhikers and bacteria will die-off in the process. This method can be very effective at killing pests but comes at the cost of losing much of the desirable life on the rock, including beneficial bacteria crucial for biological filtration.
Choosing the Right Dip
The decision on which dip to use should be based on the condition of the live rock and the goals for its use.
| Dip Type | Recommended Use | Duration (Freshwater) | Impact on Beneficial Life |
|---|---|---|---|
| Hypersalinity Dip | Routine pest removal, most live rock | Varies widely | Less severe than freshwater |
| Freshwater Dip | Extreme infestations of unwanted pests | 2-5 minutes | Significant die-off of bacteria |
Important Considerations:
- Always use saltwater mixed with quality salt mix for hypersalinity dips and RODI (Reverse Osmosis Deionized) water for freshwater dips.
- Ensure the dip water is temperature-matched to the rock's previous environment to minimize stress.
- Observe the rock during the dip to see if pests are leaving the surface.
- After dipping, rinse the rock with saltwater matching your display tank's parameters before adding it to the aquarium.
- Be prepared for a potential cycle in your tank if using a freshwater dip, as significant beneficial bacteria loss can occur.
Dipping live rock is a valuable tool for aquarists to ensure they are only introducing desirable life into their tanks.
