Cermedia MarinePure Biofilter Media

Cermedia Marinepure Every man-made aquatic ecosystem, be it a reef tank, a tropical freshwater aquarium, or a backyard pond, works on a similar principal – the natural processes occurring in a confined environment strive to achieve chemical balance, essential to sustain the life that they host. In order to maintain that equilibrium, aquarists use several types of filtration devices in their systems. No matter the environment, the most important and efficient type of filtration is biological – colonies of beneficial bacteria that break down harmful ammonia (NH3) originating from uneaten food, fish waste, and other decaying matter, into less toxic Nitrites (NO2), and later to Nitrates (NO3), in a process known as the nitrogen cycle. These bacteria occupy all surfaces in a fish tank – aquarium glass, décor, plants, and, in reef tanks, live rock. The aquarist’s goal is to provide an optimal surface on which the bacteria to grow and the best way to build healthy colonies is to use various types of biological media. The product I am showcasing today, a ceramic media, is my personal choice for both saltwater and freshwater tanks, prime “real estate” for nitrifying bacteria to grow.… More:

Steve Tyree Books: Now in Digital Format

Announcing the conversion of two Steve Tyree print books, which have been out of print for a few years, to ebook format. They are both available for purchase and download at reef farmers. The first is: Volume 1 of the Coral Maintenance Advanced Techniques: The Environmental Gradient Cryptic Sponge and Sea Squirt Filtration MethodsCaptive-Maintenance-Advanced-Techniques - reefs As the website states: This eBook describes a natural captive filtration system that was developed by Steve Tyree during the late 1990’s. The system is based on setting up low lighted or non-lighted cryptic areas where low light sponges, sea squirts and bivalves can proliferate. Aquarists can even setup a zero plumbing reef system. The electrical running costs of such a system are very minimal. The eBook details the discovery of the method starting from where it all began in 1996/1997.… More:

The flow diffuser and a cable protector are included. It is available now, and comes in three different sizes: 1350gph, 1950gph, 2450gph.… More:

Italian Marine salt Equo’s Essenza Reef

2014_11_sale_marino_equo_essenza_001 I started using the Equo‘s Essenza Reef salt a few months ago, and today I am here to share my findings. I was a little hesitant to try out this product, as none of the marine hobbyist I know, and whose tanks I can appreciate, have ever used it. But on the other hand, Equo has been surprising me lately – their new products are receiving many positive comments from other aquarists and retailers following my reviews.… More:

Wave pump Sicce XStream-E


  At the beginning of the year, Sicce presented their new adjustable-flow Sicce XStream-E pumps. I’ve been using one for the past few months, and now I’m ready to write a review. After reading about its declared flow rate, I was surprised to see how compact it was – a  tiny 8500/l electronic pump, not quite as small as the Voyager Nano 1000 e 2000, but still quite impressive.… More:

AquaIllumination Prime LED Aquarium Light Review

Ai Prime

Aquarium lighting has undergone a revolution in recent years, overwhelmingly because of the introduction of high power light emitting diodes, or LEDs. Being involved with high-end residential construction business, I’ve  witnessed LEDs “rise to dominance” in a relatively short period of time. While the aquarium and horticulture industries were among the first to adapt this new source of artificial light, home improvement businesses quickly followed, and went over and beyond with the introduction of home automation systems, where electronic devices are connected to a central hub and can be remotely accessed and controlled through an interface installed on computers and mobile devices. These days, a cellphone-controlled light bulb or an advanced smoke detector that sends text messages to home owners whenever it detects carbon monoxide are a reality within reach of the average consumer. Moreover, the technology changes so quickly, it drives prices down to the point that nowadays, an LED is a common technology most people come into contact with it in everyday life . Fish tank lighting manufacturers, trying to keep up with the trend, implemented at least some level of automation into their fixtures, most often through auxiliary controllers and wireless hubs that consumer had to pay extra for. Until now … … More:

Is the Internet a Viable Resource for Marine Aquarium Research?

Virtually since the advent of the internet, there’s been a tendency in our hobby to rate the reliability and trustworthiness of online content beneath that of print-format materials—books, magazines, and so forth. But is this assessment really fair?The general premises behind this viewpoint are: Anyone with a computer and internet connection can post anything they want online, whether or not he or she has the requisite expertise to expound on the subject. Online articles and posts are seldom given professional editorial treatment and/or subjected to peer review, so you can’t trust that they’ve been vetted properly for accuracy. There tends to be an “echo-chamber effect” online, so inaccurate or outright fallacious information appearing on one site can be picked up immediately by others and repeated ad nauseam, creating the false impression of consensus on the information/viewpoint. Now, there’s truth to each of these arguments, but as someone who’s made his living as a writer/editor for nearly 20 years (primarily in print format) and once served on an editorial committee that reviewed book submissions for a major retail pet chain, I can say with some confidence that print materials have their limitations as reference sources, too. Among them: Just as with online materials, print books and magazines are no more reliable or accurate than the writers and editors who produce them. You can’t assume that just because someone went to the effort to produce something in hardcopy, the information it contains was properly vetted. is the world's leading destination for sustainable coral reef farming and the aquarium hobby. We offer a free open forum and reef related news and data to better educate aquarists and further our goals of sustainable reef management.
