Frequently Asked Questions
What are the optimal water parameters for my reef tank?
The optimal water parameters for a reef tank generally include: Temperature: 76.8-78°F; pH: 8-8.4; Specific Gravity: 1.026; NO3: 15-25 ppm; Calcium: 420-450 ppm; Alkalinity: 8.5-9 dKH; Magnesium: 1500 ppm; Phosphate: 0.05-0.09 ppm. Regular testing and adjustments are key to maintaining stability.
How do I maintain stable water quality?
To maintain stable water quality, it's crucial to perform regular water changes, monitor your tank parameters weekly, and adjust your dosing based on test results. Strive for consistency; make changes gradually rather than drastically. Utilize a protein skimmer, filter socks, GFO, and Chaeto in your sump for effective filtration.
How do I dose for calcium, alkalinity, and magnesium?
Calcium is dosed using Calcium Chloride in a 5-gallon container using a Bubble Magus dosing pump. Alkalinity is dosed with Sodium Hydroxide, also in a 5-gallon container, via the same dosing pump. Magnesium levels are maintained through water changes, so it’s rarely dosed directly. Adjust your dosing based on weekly tests.
Are there other supplements I should consider?
You might consider dosing trace elements like Manganese, Iron, and Iodide, as well as phyto/pods that you can grow yourself. Some reefers also use products like DIY Coral Snow for additional nutrient input.
What is the recommended water change routine?
Perform a water change of about 20% weekly, which takes approximately 15 minutes for a typical size like 45-gallons. This involves draining old water into the sump, replacing it with fresh saltwater, and ensuring all equipment is switched back on afterward. Keeping two vertical 50-gallon pails for RODI and saltwater respectively can streamline this process.
How do I deal with a potential algae issue?
To address algae issues, maintain optimal nutrient levels (NO3 and PO4), utilize a good protein skimmer, and implement a GFO reactor to control phosphate levels. Keeping a clean routine, including changing filter socks regularly, can also help reduce nutrient loads that fuel algae growth.
What lighting schedule should I have for my reef tank?
For a display tank, a light schedule of 12 hours for blues and 10 hours for full-spectrum (AB+) is ideal. The schedule should ramp up and down gradually to simulate sunrise and sunset, which benefits coral and fish health. Optionally, include a moonlight feature for one hour at the end of the day.
How do you ensure proper coral growth and health?
Providing a stable environment with proper lighting (like Ecotech Radion LEDs on a modified AB+ schedule) and maintaining good water parameters is essential for coral health. Regular feeding and supplementation for certain corals, avoiding overpopulation, and ensuring good flow and light coverage will contribute to their growth.
How should I feed my tank inhabitants?
Feed your fish a mix of frozen mysis and brine shrimp infused with vitamins like Selcon, along with high-quality flake or pellet foods daily. It's also beneficial to feed herbivorous fish fresh greens such as Romaine lettuce several times a week. Corals can be fed with specific coral foods if desired.
Is quarantine necessary for new fish?
Yes, it's highly advised to quarantine new fish before introducing them to your display tank. This practice helps prevent the introduction of diseases to your established tank and ensures you monitor their health before they interact with your existing inhabitants.
