How to Grow Corals Quicker: Effects of Various Alkalinity Concentrations on Rates of Zooxanthellae Photosynthesis
For corals to grow at their best, many chemical and physical conditions must be optimized. Dana Riddle examines the effects of varying levels of dissolved bicarbonates on coral photosynthesis and growth.
Walking through big-box home improvement stores, we see an increasing selection of LED bulbs. Are any of these bulbs suitable for aquaria? Dana investigates seven LED lamps.
From flow to power consumption, noise levels to heat transfer, Dana Riddle puts the Tunze Turbelle Nanostream propeller pumps through their paces in his extensive review.
Can corals thrive on light and inorganic nutrients alone? Preliminary research suggests scleractinian corals require an external organic food source in addition to light and inorganic nutrients to maintain normal growth.
Dana Riddle reports about Hawaii's highly publicized 2015 mass coral bleaching event, its (unreported) recovery, and the science behind these phenomenons.
We are all familiar with shallow coral reefs. Growing in warm, clear waters, these colorful ecosystems are easily accessible to divers and snorkelers alike. What is less known is that coral reefs extend into deeper waters, up to almost 200 meters. In these gloomy depths, corals have adapted to low light levels, cold water and elevated nutrients.
As much as you can learn from reading books, magazines, blogs, and forums, nothing comes close to hands-on experience. Bruce York's journey with reefkeeping was a fraught with pitfalls and detours, but it's culminated in this beautiful 150 gallon reef.
Our Editor in Chief, Terry Siegel, is reinvesting in reefkeeping in a big way! After years of trying to make do with a 90-gallon reef, he realized it wasn't enough to satisfy his reefkeeping passion ... so he has restarted his famous 10-foot long reef tank.
Symbiodinium (AKA zooxanthellae) is the engine that spurs much of coral reef growth. From anatomy to clades, parasitic zoox to coral fidelity, Dana Riddle updates us on this powerhouse symbiont.
When we talk about the history of the marine aquarium, we often praise people such as Lee Chin Eng, Peter Wilkens and Jean Jaubert, who did pioneering work in the 20th century. Their innovations and vision helped give rise to the popular marine aquarium hobby we know today. What few people know, however, is that Victorian England saw an aquarium craze 165 years ago, when much ground-breaking work was done. Some of the pioneers of the marine aquarium from that time are George Johnston, Robert Warington, Anna Thynne, William Lloyd and Philip Henry Gosse. In this article, I will detail their work, including the trials and tribulations, which represents some of the early attempts to maintain a balanced marine aquarium.
The diversity of Tridacnid available to hobbyists has expanded in recent years, and so has the taxonomic confusion among aquarists and researchers alike. James W. Fatherree sheds light on the "new" giant clams.
Feature Study: Effects of rock preconditioning and irradiance on growth of crustose coralline algae in aquaculture
Due to its high commercial value, live rock is a promising candidate for aquaculture. This poses interesting challenges, as our knowledge of live rock development in aquaculture is limited. The current preliminary study investigated the effects of rock preconditioning and irradiance on the growth of crustose coralline algae (CCA), a desired group of benthic calcifying algae.
EcoTech Marine's VorTech pumps recently underwent its first major product evolution. Dana Riddle thoroughly evaluates the new MP40 QuietDrive propeller pumps for their functionality and performance.
Dana Riddle's sixth Coral Nutrition article examines the effect of alkaline earth (e.g. calcium and strontium) and other metals on corals – including some rather surprising information.
Reefs are tricky balancing acts of livestock largely learned through trial and error. Fortunately, we have successful aquarists to guide the way. James shares his experiences with stocking a large mixed reef.
