Frequently Asked Questions
What is the best way to set up a reef tank?
To set up a successful reef tank, start with a suitable aquarium size, ideally at least 75 gallons for stability. Choose a modified Berlin filtration method using live rock and live sand, ensuring a good skimmer and possibly adding refugiums for nutrient export. Make sure to cycle the tank properly before adding any organisms.
How do you maintain water parameters in a reef tank?
Regular water testing is essential. Maintain calcium (Ca) between 390-410, alkalinity (Alk) around 11 dKH, and keep pH between 8.21-8.30. Use additives like calcium reactors and buffer solutions, and perform regular water changes to keep nutrients like NO3 and PO4 at zero.
What is a DSB and why is it important?
A Deep Sand Bed (DSB) is a substrate layer of 3.5-4 inches of sand, which helps in biological filtration. It supports beneficial bacteria that process nitrates and other harmful substances, thus keeping your tank healthy.
What is the role of refugium in a reef tank?
Refugiums serve as a separate area for growing macroalgae, which absorbs nitrates and phosphates, aiding in nutrient export. They also provide a safe habitat for microfauna, which can help create a more balanced ecosystem in the main tank.
How frequently should I change the water in my reef tank?
Bi-monthly water changes of about 20 gallons are typically recommended. However, adjust the frequency based on water quality tests and overall tank health.
How should I feed my corals and fish?
Feed fish twice daily with a varied diet, including Mysis shrimp, pellets, and seaweed. Corals should be fed live phytoplankton and rotifers daily, with approximately 1 - 1½ cups of phytoplankton and about 1 gallon of rotifers added before the lights go off.
Is it necessary to supplement fish food with vitamins?
Yes, soaking fish food in vitamin supplements like Boyd's Vita-Chem a couple times a week can help boost health and prevent disease.
What type of lighting is best for a reef tank?
A combination of metal halide bulbs and VHO (very high output) fluorescent bulbs is effective. For instance, using 250 watt metal halide bulbs supplemented by 140 watt VHO will provide sufficient intensity and spectrum for coral growth.
How does a calcium reactor work and why is it important?
A calcium reactor helps maintain stable calcium levels by dissolving calcium carbonate media in a water solution, which is then injected into the tank. This is crucial for stony coral health as it promotes skeletal growth.
What kind of filtration setup should I have?
A layered filtration system including protein skimmers, mechanical filtration, and chemical filtration (like activated carbon) should be employed. The Lifereef skimmer and sump system can enhance overall water quality.
What should I do if my corals are not growing?
Check and stabilize water parameters regularly; ensure proper lighting and flow. Consistent feeding with live phytoplankton can also encourage growth. If issues persist, consider reducing bioload or increasing water change frequency.
How can I prevent algae growth in my reef tank?
Keep nutrient levels (nitrates and phosphates) low through regular water changes and using refugiums for nutrient export. Properly functioning skimmers and good circulation will also help manage algae growth.
