Frequently Asked Questions
What type of protein skimmer do you use and why did you choose it?
I use a Deltec AP 902 protein skimmer for my tank. I chose this skimmer because the tank has a high bioload due to the number of fish and the amount of food added daily. The former skimmer was unable to adequately remove enough organics, and I found the performance of the Deltec AP 902 to be excellent for my needs.
How do I maintain my phosphate reactor?
I have a My Reef Creation's phosphate reactor that typically contains about 500ml of phosphate media. I change the media every four to five weeks to ensure optimal performance and to control phosphate levels due to the high fish load and feeding in my aquarium.
What is the best way to set up a refugium in a reef tank?
To set up a refugium, ensure it is connected to your main tank's overflow. In my system, one of the main overflow drains goes directly into the refugium where it passes through macroalgae before draining back into the sump. This process not only adds natural filtration but also provides a food source for fish from the organisms grown in the refugium.
What is your water circulation setup?
My main pump is a Dolphin 4700, which moves approximately 3000gph from the basement sump to the main display tank. I have three outlets that split water flow between two Sea Swirl devices and another outlet positioned behind the rockwork to enhance circulation at lower levels of the tank.
How do you ensure water temperature stability in your tank?
I use a ½ horsepower Aqua Logic chiller to maintain the water temperature in the safe range of 77-79°F. Proper chiller sizing and placement are crucial to controlling temperature effectively.
What lighting do you use for your reef tank?
I use two 400-watt 10K Ushio metal halide bulbs, which provide the main lighting, along with four 140-watt VHO actinic bulbs for supplemental lighting. This combination enhances the visual appeal of the tank and supports good coral growth.
How do you manage your tank's water parameters?
I regularly test my tank’s parameters weekly to keep everything in check. My typical levels include specific gravity at 1.025, temperatures between 77-79°F, and calcium between 360-440 ppm. Regular water changes and monitoring help me make necessary adjustments for optimal coral health.
What does your photoperiod look like?
The photoperiod begins with the VHO actinics, which come on about 30 minutes before the metal halides start at 1:00 PM. The halides run for approximately nine hours, and then the actinics run for another 30 minutes after the halides turn off.
What routine maintenance do you perform on your tank?
Basic maintenance includes topping off evaporation with kalkwasser, which I do at about four gallons per day. I also perform a 25-gallon water change weekly, clean the skimmer's cup two to three times per week, and monitor water parameters. This routine helps maintain a stable environment for my marine life.
Why do you perform frequent water changes?
I perform weekly 25-gallon water changes to address the heavy bioload from my fish and the amount of food I provide them. Regular water changes help to maintain water quality and reduce the buildup of harmful substances in the tank.
