Frequently Asked Questions
How do you maintain your water quality?
I rely on ICP (Inductively Coupled Plasma) testing every two months to check the condition of the reef water and RODI supply. I perform two 25L water changes each week and use Hanna checkers and Salifert kits for random monitoring in between ICP tests.
What parameters do you track for your reef tank?
I track several parameters including temperature, pH, specific gravity, nitrate (NO3), calcium (Ca), alkalinity (Alk), magnesium (Mg), and phosphate (PO4). My ideal readings are: Temperature: 27°C, pH: 8.2-8.3, Specific Gravity: 1.025, NO3: 8, Ca: 440-450, Alk: 7.5, Mg: 1350-1400, PO4: 0.04.
What kind of salt mix do you use?
I use Tropic Marin Bio-Actif salt. I've been using it since 2015 because it mixes well and is quick to dissolve, making it effective for my reef tank.
What filtration methods do you use?
I use a combination of filter socks, a Reef Octopus Elite 150sss skimmer, an AF110 media reactor, and a Nyos 2L torq reactor. Additionally, my sump contains Miracle Mud to enhance nutrient export.
How do you manage calcium, alkalinity, and magnesium levels?
I use a calcium reactor along with a KHG monitor/doser to keep tabs on my parameters. I set my alkalinity at a target of 7.5KH and use a Kamoer X4 dosing pump to add calcium and trace elements as needed.
What do you use for carbon and phosphate filtration?
For phosphate filtration, I use Rowaphos to keep phosphate levels in check and help maintain overall water quality.
What lighting system do you use for your reef tank?
I use a combination of 2 Orphek icons, 2 Quanta Miso Blues, a Reef Factory blue bar, and an actinic bar, alongside a Radion X15 for my refugium. The lighting is set on a schedule, following a gradual ramp-up to peak brightness during the day.
What is your lighting photoperiod?
For the display tank, the lighting schedule is as follows: Blue actinic bars from 6:00 am to 11:00 pm, icons peak at lunchtime from 9:00 am to around 8:00 pm. The refugium lights are on from 9:00 am to 8:00 pm.
What do you feed your fish and corals?
I feed my fish frozen food twice a day and Ocean Nutrition pellets once a week. For corals, I provide coral food once a week.
How do you decide on stocking your reef tank?
I aimed to create a full, natural-looking SPS tank. Initially, I selected corals that I felt would contribute to this look, but I learned over time that coral placement and maintenance are crucial to prevent overgrowth and shading.
What are some common challenges you faced with coral and fish stocking?
I regretted stocking too many stags and Montiporas, as they grew large and created shading issues, which required me to rescape my tank several times. It's important to consider how quickly certain coral species can outgrow their space.
