Frequently Asked Questions
How do I properly set up a new reef tank?
To set up a new reef tank, prepare all necessary equipment first. Ensure your tank has a stable stand and level the tank on the stand. Use a high-quality pump, like a Sequence Dart, and install a sump system to manage filtration. Add live rock and sand after ensuring proper placement. Allow the setup to cycle for several weeks before adding any livestock.
What type of substrate should I use for my reef tank?
A reef tank commonly uses aragonite sand as substrate as it helps buffer pH and provides a habitat for beneficial bacteria. A one to two inch sand bed is standard, allowing for both aesthetics and a suitable environment for wrasses.
What is the best way to clean my tank?
Regular maintenance involves cleaning the glass with a magnet scrubber, performing monthly water changes (at least 100 gallons for a 300-gallon tank), and changing filter socks every 3-4 days. Additionally, stir the sand bed to keep detritus from accumulating.
What water parameters are ideal for a reef tank?
For a reef tank, the following parameters are ideal: Calcium ~ 380 ppm, Alkalinity 9-10 dKH, Nitrate and Nitrite should be undetectable, Phosphate should be maintained around 0.04 ppm, Magnesium ~ 1450 ppm, Specific Gravity ~ 1.025, Temperature 77-78°F, and pH between 7.9-8.0.
How do I maintain my water quality?
Use a Reverse Osmosis/Deionization (RO/DI) unit to ensure high-quality water. Additionally, running UV sterilization and a canister filled with activated carbon helps maintain water clarity and quality. Test water parameters weekly or monthly as needed and perform routine equipment checks.
What type of lighting is best for an SPS-dominated reef tank?
A combination of Metal Halide lights and VHO actinic bulbs is effective for SPS tanks. Ensure that the lights are positioned to maximize PAR (Photosynthetically Active Radiation) across the tank. A photo period that mimics natural conditions, such as having Metal Halides run from 1 p.m. to 6:30 p.m. with gradual light ramp-up, helps coral health.
What filtration system should I use?
Use a sump system that includes a protein skimmer, filter socks, and possibly a calcium reactor. A Deltec AP902 protein skimmer is recommended for efficient organic removal. Regularly replace filter socks and clean the sump to maintain optimal conditions.
How often should I feed my reef tank inhabitants?
Feed your reef tank inhabitants once daily using a variety of frozen foods such as Mysis shrimp, brine shrimp, Cyclop-Eeze, and coral food for diversification. Ensure LPS corals are fed after the lights go off to prevent fish from stealing their food.
What additional supplements do I need for my reef tank?
Regular testing of calcium, alkalinity, and magnesium is crucial. Utilize calcium reactors to maintain these levels. You can also run a Kalkwasser reactor for top-off water to support calcium and pH levels.
