For a healthy reef tank, aim for the following water parameters: Calcium at 400-450 ppm, Alkalinity around 8-12 dKH, pH between 8.1 and 8.4, Nitrate below 5 ppm, Phosphate below 0.1 ppm, Temperature between 75-80°F, and Specific Gravity around 1.025-1.027.
Ensure your sump is positioned below your tank for gravity-fed drainage. Use a powerful return pump, like the Iwaki MD70RLT, to maintain circulation. Consider incorporating features like SeaSwirl devices for rotating currents. Ensure all pipe fittings are secure and that there are no air leaks in the system.
A closed loop system provides additional water movement behind rocks and difficult areas that may not get enough flow from traditional return pumps. It helps in preventing detritus accumulation and enhances overall health by ensuring consistent water movement around all areas.
Metal halide lighting combined with actinic fluorescent lights work well for coral growth. A common setup is dual 250 watt metal halides complemented by VHO actinic tubes. Maintain a photoperiod of 10-12 hours for best coral health and growth.
Important equipment includes a protein skimmer for waste removal, a high-quality return pump, calcium reactor for maintaining calcium levels, and effective filtration like a sump with live rock. Additionally, auto top-off systems can help maintain stable salinity.
To culture phytoplankton, use clear bottles or containers with aeration to keep the water circulating. Provide light and maintain stable temperatures (around room temperature). Harvest regularly to prevent crashes and consider starting with a small number of bottles, gradually increasing as you get comfortable.
A refugium provides a safe space for beneficial organisms such as amphipods and copepods to thrive. It helps maintain natural populations that serve as food for fish and corals, and supports nutrient export through macroalgae.
To set up a macroalgae refugium, use an acrylic tank with dividers to reduce turbulence. Use a suitable grow light to encourage growth and ensure water can flow without clogging. Populate it with live rock and your chosen macroalgae for effective nutrient export.
Feed fish a variety of foods including flakes, pellets, frozen food, and live foods like baby brine shrimp. Balance the diet to prevent overfeeding, which can lead to nutrient spikes in the tank.
Regular maintenance including water changes, vacuuming substrate, and controlling nutrient levels is vital. Limit light exposure using a timer, maintain appropriate stocking levels, introduce herbivorous fish, and regularly remove excess algae manually.
