Frequently Asked Questions
What type of skimmer is used in this reef tank?
The reef tank uses a Coral Box D500 DC skimmer, which runs at 100% power and takes air from outside to maintain optimal performance.
How does the flow setup work in the aquarium?
The tank has multiple flow devices: two Jebao SW-8 pumps on opposite walls running at 60% power and a Jebao WiFi Cross Flow Pump CP-25 at 40% power at the back to effectively circulate water and prevent detritus accumulation.
What lighting system is implemented, and what is its schedule?
A custom hybrid lighting system is used, combining an ATI T5 Sun Power 8x24 with LED modifications. The lighting schedule gradually increases lighting intensity throughout the day, helping corals thrive with a mix of royal blue, violet, red, and T5 light.
How do you maintain water parameters, particularly calcium and alkalinity?
Initially, a calcium reactor (Bubble Magus CR-100WP) was used, but due to low pH issues, a Jebao DP-4 dosing pump system was implemented to add calcium, alkalinity, and magnesium for better control of water parameters.
What water treatment method is used for this tank?
The water is treated using a reverse osmosis filter (SpectraPure) followed by an ion exchange resin to lower TDS from tap water, ensuring better quality water for the tank.
How often do you perform water changes and what volume do you typically change?
Water changes are performed once a week, changing about 10% of the water to help maintain water quality and keep the aquarium inhabitants healthy.
What do you feed the fish in this reef tank?
Fish are fed once a day with minced shrimp, and once a week Reef-Roids are added to the tank, pre-mixed with a small amount of water and poured into areas of strong current.
Do you add supplements to the reef tank?
Occasionally, iodine is added to help maintain the blue color of corals, and potassium is dosed for a more vibrant red color.
What types of corals are in the tank?
The tank houses approximately 40 species of SPS corals, 20 species of LPS, several types of Zoanthus, discos, and Rhodactis.
How do you monitor coral health and growth?
Water is periodically tested through ICP MS to ensure balanced water chemistry. Corals have shown good health by exhibiting bright colors and growth, which indicates their well-being in the aquarium.
