A refugium can be set up using a separate tank or a compartment within your sump. Ensure it has a light source, as this area should promote macroalgae growth which helps filter nitrates and phosphates. Add a substrate of coral sand, about four inches deep, and include live rock or structures for habitats. Place a water pump to allow flow from the main tank into the refugium.
When selecting lighting, consider the type of corals you plan to keep, as different corals have varying light requirements. For SPS and LPS corals, intense lighting, such as metal halides or LED lights, is often recommended. A balanced spectrum, including blue light, enhances coral color and growth. Aim for a 10-14 hour lighting schedule to mimic natural conditions.
It's advisable to do small water changes weekly, typically around 10-15% of the total water volume. In your case, about six gallons weekly will help maintain stable water parameters and dilute any accumulated nutrients or waste. Aerate freshly mixed saltwater for an hour before adding it to the tank.
A protein skimmer is crucial for removing organic waste from the water before it breaks down into harmful compounds. It aids in maintaining water clarity, improves oxygen levels, and enhances overall tank health. Regularly clean the skimmer cup, ideally once a week, to ensure efficient operation.
For a healthy reef tank, aim for specific gravity between 1.025, temperature between 79 - 82ºF, pH between 8.00 - 8.25, calcium levels of 380 - 420 mg/l, alkalinity of 9 - 11 dKH, magnesium at 1400 mg/l, and undetectable nitrate and phosphate levels. Regular testing with quality test kits is essential to keep these levels stable.
Calcium and alkalinity can be maintained through regular dosing of a calcium supplement or using a calcium reactor. In your setup, using kalkwasser in evaporated water can also help balance calcium levels. Ensure to monitor your levels periodically and adjust accordingly.
Feed your tank once a day to prevent overfeeding. Offer a mix of frozen foods like brine shrimp, Mysis, and krill. Supplement daily with live phytoplankton, and provide live brine shrimp or rotifers a couple of times a week. Soaking foods in vitamins or amino acids before feeding can enhance their nutritional value.
To culture phytoplankton and zooplankton, consider using a plankton reactor. Initially set up the reactor with appropriate species like Nannochloropsis for phytoplankton and Brachionus for zooplankton, maintaining a consistent light and water flow for optimal growth. Clean the reactor every month to prevent crashes.
