If you have even worked at the retail or wholesale end of the aquarium fish industry–even for just a week–you are probably keenly aware of the threats posed by viral, bacterial, and especially parasitic diseases. Between fish collectors, breeders, distributors, stores, etc., your new fish may have crossed paths with hundreds or even thousands of …
Phytoplankton
Keeping corals and other planktivorous invertebrates in the home aquarium is easier–and one’s chances of long-term success are better–than ever before. Indeed, aquarists are now breeding species thought to be nearly impossible to keep just a decade ago. So, what’s changed? It’s certainly not as though the animals have changed. What has changed is way we care for them. Among the biggest improvements we’ve made is the greater quality and availability of specialized feeds (such as live, planktonic microalgae) for these species. Maybe the best example of this is coraliculture. Coral foods in the early days of reef aquarium keeping were quite unimpressive. As in, made out of stuff like chicken eggs. The results were generally disappointing. We pretty threw the towel at coral foods altogether until fairly recently. And corals did alright without–certainly better than in the 1990s! But corals were still rather… blah. At least compared to what we see today. Of course, to a huge extent, the mindboggling variety and dazzling colors that aquarists now take for granted have come from decades of selective cultivation by extremely dedicated farmers. That said, much of this happy development owes to our better understanding of coral nutrition. Central to this are live phytoplankton products. There are now a handful of “phyto” aquarium foods on the market nowadays. These vary from one another in several key aspects. Cost, convenience and performance are major considerations by users; arguably, it is the last of these that is most important—at least to your aquarium inhabitants! In terms of quality, the best phytoplankton products are live (rather than dead and preserved), mixed-species products. Moreover, they are completely nutritionally balanced. Products containing intact, living cells are much cleaner than those made of dead stuff. Live products also produce less pollution. Live (and multiplying) phyto actually removes waste products from the aquarium water! Clearly, there is a lot about phytoplankton for the discerning reef aquarist to know! In this section you will learn what role phytoplankton play in reef environments, why they are so nutritious and how use phyto products most effectively to reduce nutrient levels and feed pods, corals, clams and other animals in the reef aquarium.

Pods. Phyto. At AlgaeBarn, these are the bread and butter of the reef aquarium diet. And for sure, these two items form the base of most freshwater and marine food chains. Just consider OceanMagik, which is a blend of four distinctly different species of phytoplankton. Or EcoPods, which is a mixed-species (four, to be exact) …
Upgrading to the ULTIMATE Refugium Starter Pack
You might be setting up a brand-new reef tank. Maybe you’re doing some upgrades to an existing aquarium. Either way, you’ll have a lot of individual concerns to address. First and foremost, “Is this system capable of managing a large(r) bioload?” And then, “How will I deal with all of the nitrate that my biofilter …
Do Corals Really Eat Plankton?
It’s hard to say for sure which came first for reef aquarists–the emergence of high-quality coral foods, or the realization that corals actually, really, truly do eat them. Though aquarists are generally a skeptical bunch, the initial apprehension to feeding corals is pretty understandable; in all fairness, many such foods sold in the recent past …
Natural Water Quality Management for Non-Photosynthetic Reef Aquaria
There was once a time when zooxanthellate corals (especially SPS corals) were considered impossible to keep in captivity. Then advancements in aquarium lighting technology changed all that. It’s hard to imagine that there so recently was a day when marine aquarists abandoned the possibility of ever keeping Acropora–one of the most abundant genera of stony …

What Do I Need for a Saltwater Fish Tank?
Whether scouting for your first aquarium, or “graduating” from a freshwater aquarium, there is something about a saltwater aquarium that is mesmerizing. For many lifelong aquarists, that feeling of captivating awe never goes away. Thankfully, the intimidating task of learning how to actually build and maintain a saltwater aquarium system does go away. In fact, …
A Look at the NEW OceanMagik
It’s amazing how much has changed in the reef aquarium hobby since 2012. During that time, we’ve seen a surge of aquarium info resources on social media, a deluge of new designer strains of stony corals, soaring attendance at trade shows (at least until this year’s pandemic), revolutionary aquarium monitoring and automation devices, big advancements …
Corals in a Box of Water: Creating a Natural Reef Tank
We’ve come a long, long way in advancing natural marine aquarium keeping. Those of us who started out in the 80’s with barren “aquascapes” dead coral skeletons and crushed coral bottoms might look back with amazement at how so much has changed so fast. Just recall how many developments have taken place over the last …

Gutloading Live Microcrustaceans
In the sense that very, very few animals specialize to eat only one thing, all animals are omnivores, and prefer live foods. For example, when herbivores graze on turf algae, they’re not just eating algae but rather the entire “epilithic algal matrix” which includes those bacteria, protists, etc. that live on the algae. Similarly, in …
A Closer Look at Carotenoid Pigments
Meeting the dietary requirements of a reef aquarium–a delicate microcosm filled with diverse organisms with varied nutritional needs–can be a daunting task. One might find it hard enough just to provide the right balance of those basic components: Carbohydrates, lipids and proteins. But then there are all those other things to concern yourself with, such …

Phytoplankton Species and their individual Strengths
When purchasing live foods for your tank, many people simply take the shop employee’s advice when handed a jar of unidentified copepods for their reef tank. Most do not research into the different species of copepods, we just understand that they are a major element of our clean up crews and that our fish love …

Gorgonians in the Marine Aquarium
It should go without saying that the hermatypic, stony, reef-building corals will dominate most reef aquaria. Thankfully, so long as (1) key water parameters are monitored, (2) the appropriate light conditions are provided and (3) nutritious planktonic foods are present, these beautiful plant-animal symbiotic combos easily flourish even in the care of novice hobbyists. Especially …
Eliminating Detritus in the Refugium
Ever feel like no matter how much time you spend cleaning your tank, it can never really ever get clean? Detritus build-ups can be especially frustrating as they seem to come from nowhere and seriously compromise the healthy and natural appearance of an otherwise beautiful exhibit. One solution is to construct the system in such …
Phytoplankton
The first link in a food chain is always a primary producer, like phytoplankton (i.e. algae, plants, various types of bacteria). This is because all other living things—consumers—are incapable of synthesizing organic substances from inorganic ones. Primary producers rely on inorganic sources of energy (sometimes chemical, but usually from light). Using this energy, they take …
Phytoplankton, Macroalgae, or BOTH?
As marine aquarists, we might think of algae as being divided into three (maybe four) distinct categories: the benthic (i.e. bottom-dwelling) microalgae, the open-water microalgae and the macroalgae. The first group consists of the film/turf-formers, the second group consists of the phytoplankton and the third group consists of the larger, plant-like seaweeds. The first group …
Kickstarting Your New Refugium
Whether it’s just been installed as part of a bone-dry, newly set up aquarium system or as an add-on to a well-established, heavily stocked reef tank, you’ll probably want your new refugium to be operating at its peak performance from the onset. Seeding the right beneficial organisms in the right amount at the right time …
A Copepod Cornucopia: How to Maintain a Continuous Live Food Source in Your Reef Aquarium
Some of us aquarists are satisfied just to find a pod or two in our systems—just to know that they’re still there! Then again, some of us are always reaching for that endless bumper crop. Those who push for ever higher copepod yields might indeed be on to something really big. Let Them Eat Pods …
Using Phytoplankton to Control Bad Algae
Despite their lush appearance, natural coral reefs are extremely nutrient-poor environments. Not likely to be able to grow too much bad algae. Corals everywhere should be just fine with that, since it means less pressure to compete for space with benthic (that is, growing on the sea floor) microalgae. Planktonic microalgae, on the other hand, …
Boosting Reef Aquarium Diversity With Live Phytoplankton
Saltwater aquarium keeping certainly come a long way in a relatively short period of time. Heck, we only started widely using live rock about a quarter century ago. Nowadays, almost any coral reef species (provided that it is not protected) can be obtained in the aquarium livestock trade. Sadly, however, not all of these can …
