Frequently Asked Questions
How do I install an overflow system in a reef tank?
To install a homemade overflow system, first, glue a box to the inside back wall of the tank using silicone. Once dried, drill a hole through the back wall and the overflow box to accept a bulkhead fitting. Ensure the bulkhead fits snugly and securely to allow proper water flow.
What type of sump is suitable for a small reef tank?
A simple 5-gallon Rubbermaid sump can be effective for a nano-reef. It should contain a bubble trap, like a micron filter bag, and a heater with a return pump. The sump serves to filter excess particles from the water and manage water changes effectively.
What is the best maintenance routine for a small reef tank?
For a small reef tank, perform a monthly 5-gallon water change using de-ionized water and appropriate salt mix. Clean the micron bag every 2 months, and clean the return pump every 3-4 months to ensure optimal functioning.
How often should I test my tank's water parameters?
Perform regular tests for parameters such as ammonia, nitrite, nitrate, pH, alkalinity, calcium, and magnesium weekly or bi-weekly initially, then adjust frequency based on stability or fluctuations.
What are the ideal water chemistry parameters for a reef tank?
Maintain the following ranges for a healthy reef tank: Salinity at 1.025, temperature between 76°F and 78°F, ammonia at undetectable levels, nitrite at undetectable, nitrate ideally under 10ppm, alkalinity at about 12 dKH, calcium between 425 and 450 ppm, and magnesium at around 1500 ppm.
How can I manage evaporation in a small reef tank?
To manage evaporation, consider creating an automated top-off system using a float switch connected to a pump. The float switch can activate a pump to add fresh water from a reservoir, maintaining salinity and reducing stress on your tank's inhabitants.
What feeding schedule should I follow for corals and fish?
Feed your fish twice weekly using high-quality marine flake food supplemented with live brine shrimp occasionally. For corals, add DT's Phytoplankton 2-3 times weekly to help with nutrition.
Which additives are essential for maintaining water quality in a reef tank?
Key additives include: Calcium (weekly), Alkalinity (twice weekly), Magnesium (every 2 weeks), and Iodine (weekly). These help balance the chemical levels that corals and other inhabitants need to thrive.
What type of lighting is best for a nano-reef tank?
Metal halide lighting is recommended for its ability to closely mimic sunlight. A compact system, like a 150-watt HQI metal halide, is ideal for a 20-gallon reef tank, running on a photoperiod of 6 hours each day.
How should I position the lighting above my tank?
The light hood should be hung at least 10 inches above the tank to provide adequate space for heat dissipation and prevent overheating the water.
