#10: Imitating Natural Light Quality, Intensity, and Dosage in a Reef Aquarium - Do We Really Want To?
By Dana Riddle
When it comes to reef aquariums, Mother Nature has always been the de facto benchmark aquarists aspire towards. Dana investigates in great detail the quality and quantity of light over natural reefs in order to lay the groundwork to answer the age-old question: what is the best light for captive corals?
By Tim Wijgerde, Ph.D.
At present, several factors which influence the growth of scleractinian corals in aquaculture have been identified. These are known as light, water flow, water quality, and nutrition. This article will focus on nutrition, and describe the various ways in which corals feed. It will summarize the latest scientific findings about this topic, and present practical information on how to maximize coral feeding rates in the aquarium. This will promote efficient, sustainable coral aquaculture, and help the aquarist to maintain healthy corals at home.

Overall toadstools are attractive, hardy, and easy to propagate, making it easy to see why they are a long-time hobby favorite.
#7-1: PAR Meters and LEDs - How Accurate are the Measurements? A Comparison of Three Meters and Lux to PAR Conversion Factors for LEDs
By Dana Riddle
How do PAR meters stack up to one another? Dana delves into the data comparing and contrasting three light meters and gives us his take on the results.

Continuing in the same vein as my previous LED lighting tests, this article presents data on light intensity and spread along with spectral plots for several new LED fixtures.

Conventional reefkeeping wisdom says live corals should not coexist with big angelfish and butterflyfish. Don't tell that Bryn Roberts. With careful selection of fish, corals, and invertebrates, Bryn pushes the boundaries of "reef safe." Large, colorful coral colonies thrive in the presence of rare angels and butterflies.

While not a panacea or miracle drug, chloroquine is experiencing resurgence in popularity for use in fish-only aquariums and quarantine systems to treat a variety of problems ranging from Cryptocaryon to Aiptasia anemone infestations.
By Paul Bruns
There are reef aquariums, then there are REEF AQUARIUMS. Paul Bruns' 427 gallon captive reef is a true masterwork of aquascaping, husbandry, technology, and technique.

LED lighting has come a long way and the new generation of LED fixtures is delivering on the promise of LED technology, and control features. As usual, the users need to consider their own applications to determine the best one for the situation. Hopefully this data will be helpful in making your decisions.

It's been a little over a year since Ecotech Marine introduced the Radion LED light. The Radion made big waves with aquarists and quickly ascended to mass popularity. In January 2013, Ecotech Marine began shipments of their latest and most powerful incarnation of the Radion platform: the XR30w Pro. Advanced Aquarist takes a closer look at the Pro.

With the advent of new technology, aquarists are able to customize light spectra with great flexibility. However, our knowledge of how light spectrum affects aquarium life, including corals, is still limited. Here, we show the effects of two light spectra, emitted by Light Emitting Diode (LED) and Light Emitting Plasma (LEP), on the growth of ten commercially important scleractinian corals. It appears that the effect of spectrum is highly species dependent, and that most efficient coral growth is invariably attained at low irradiance. The results from this study can be used to optimize sustainable coral aquaculture.
