Water Parameter Management
We are using a variety of items to maintain water parameters and key elements. Water parameters are kept in line using the Octopus 3000 to monitor ORP, temperature, pH and salinity. This helps us to know at any given time if we are having any sort of issue with the system so we can quickly react to catch and fix any potential problems.
For alkalinity, calcium and magnesium supplementation we are using a combination of Kalkwasser and a Korallin calcium reactor. Because of some of the colonies’ size in the main display I have found this to be the most effective way for us to safely maintain consistent levels in the tank around the clock.
Water Parameters
- Specific gravity: 1.025
- pH: 8.0 to 8.2
- Calcium: 400 ppm
- Alkalinity: 8 to 9 dKH
- Magnesium: 1300 ppm
- Phosphate: undetectable
- Temperature: 77 to 78° F
Temperature Control
Because heat is a major concern for small-polyped stony corals, we use a 1 HP chiller to help maintain a consistent temperature. The tank’s water temperature is monitored and controlled by the Octopus 3000 and is set to maintain the display between 77-78° F year round. As the corals have continued to grow, managing parameters such as the water temperature becomes more of an issue. Adding the chiller has given me a peace of mind that this sensitive parameter is being maintained at all times.
