Featured Coral: Fat Head Dendrophyllia

This Featured Coral of the Week comes to us from Joey Nichols at Joe Knows Reefs. Common name: Fat Head Dendro Scientific name: Dendrophyllia fistulata  Dendrophyllia fistulata is a non-photosynthetic coral which does not contain zooxanthellae in it’s tissue thus having to derive all of it’s nutrition from organic matter.  Since they do not require sunlight for growth, these coral are normally found inside and along cave walls and overhangs.   In the aquarium, this coral requires feedings of meaty foods such as brine shrimp and mysis shrimp etc at a frequency of about 2-3x weekly. Origin area: Indo Pacific Care level: moderate due to requirement of frequent feedings. Unlike “sun coral” it can be easily trained to stay open pretty much all day.  These corals

An Ultra-Low-Nutrient System for Acropora and other SPS

Top down shot of Acropora microladosWelcome to the next level of coral care. By now I am assuming you have at least understood all the key general practices to maintain some of the hardier corals, from soft corals to large-polyp stony (LPS) corals to some of the more rugged small-polyp stony (SPS) corals. Each category of livestock can be classified into various requirements for the piece of ocean environment you are trying to simulate. Oftentimes we tend to generalize that all parts of the ocean are the same, but as you become educated about the livestock you are trying to maintain, you will understand that there is no single recipe to make everything thrive and flourish in the same tank.Review time So let us review some of the key attributes we, as responsible hobbyists and nature fans, must familiarize ourselves with in order to provide a sustainable environment. The most common aquarium parameters are the following: 1. Tank dimensions Volume (amount of salt water for stability) Depth (impacts light penetration and available environmental zones) Size (impacts aquascaping, flow, lighting choices, growth) 2. Lighting Type: metal halide, T5, LED, or hybrids Spectrum (10,000 to 20,000 Kelvin) Intensity (lux) Photosynthetically Active Radiation (PAR) Photosynthetically Usable Radiation (PUR) Photoperiod (hours) 3.

Coral Atoll: A New App for Reef Enthusiasts

[embedded content] Atoll is a new app available for reef aquarium and diving enthusiasts to download on the iPhone. Atoll is an interactive mobile app which includes a comprehensive database of coral.  Atoll provides vibrant photos and detailed information allowing users to more easily identify coral which they encounter on a dive or purchase as an addition to their aquarium.  This can be critical information especially when dealing with corals which exhibit aggressive behavior and could potentially wreak havoc in your aquarium if placed in close proximity to other species.  Atoll also provides useful information to hobbyists relating to appropriate water temperatures and pH levels for your own aquarium. Atoll also allows users to submit photos of unknown coral for the community to identify. This is

Top 10 Tips For Keeping a SPS Reef Tank

Top 10 Tips For Keeping a SPS Reef Tank Let’s face it.  Keeping a reef tank is not a simple chore but there are some basic tenants one can follow to optimize the chances for success.  With over 20 years in the hobby I have learned a lot from both my successes and failures.  Below are My Top 10 Tips For Keeping a Successful Reef Tank dominated by SPS.  I will dive deeper into each item on the list in future blog posts so stay tuned. The List Stability – It is critical to have stability for parameters such as salinity, nitrate, magnesium, and calcium. And perhaps most important in my book for SPS is keeping alkalinity at a consistent level. Strong Lighting – I have had a lot of
