With the advent of smart phones, aquarium photography has changed significantly over the last few years. Today, social media and aquarium fora are filled with decent quality images of freshwater and marine life. The era of DSLR cameras has still not passed, however. Not only do these cameras provide higher quality images, they also offer the photographer plenty of additional creative options. One of these is time-lapse photography, which I will discuss in detail in the following article.
How to Grow Corals Quicker, Part II: Combined Effects of Water Velocity and Alkalinity Concentrations
If we want to grow corals more quickly, it helps to understand the interplay of the many variables that affect corals. Dana explores the relationship between alkalinity, water flow, photosynthesis, and nutrients.
In his travels, Terry highlights the excellent reef stores he encounters. Reef LFS can be found in some of the most surprising locations. The people and passion is what make a store great.
Two decades of commitment and a lot of modern technology has helped Tony (AKA "Reef Bloke") bring to life a captive ecosystem that brims with vibrant coral reef life.
Product Review: Apogee Instruments' MQ-500 Quantum Meter with Notes on Why Measuring Light Intensity is Important
Dana reviews Apogee's premium MQ-500 Quantum (PAR) Meter and explains why reefkeepers should measure the light levels in their aquariums. Apogee has also introduced a new quantum meter specifically designed for underwater aquarium use.
Advanced Aquarist welcomes our newest contributor, Alex Wilson. Alex describes how to quarantine marine-fish by combining hyposalinity and the "Transfer Method II" to prevent the two most common and virulent fish diseases: Ich and flukes.
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.
