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) …
Benefits of Live Copepods
Challenges are good. For most of us, the considerable trials of keeping a tankful of healthy aquarium livestock keep us interested and engaged in the hobby. That being said, some of the regular problems encountered by aquarium hobbyists can be quite intimidating; arguably, the greatest challenges of keeping healthy marine aquarium systems are (1) meeting the nutritional demands of finicky/specialized eaters and (2) controlling detritus build-up and nuisance algae growth. Fortunately, both of these constantly pressing issues are effectively approached with the use of live copepods.
Extremely nutritional and capable of reaching extraordinarily high population densities, copepods are nature’s consummate food packets. They range from important to critical in pretty much all aquatic/marine ecosystems, transferring nutrients and food energy from algal/bacterial primary producers up the food chain to filter-feeding fishes and invertebrates. Their role as trophic intermediaries is entirely replicable in captive systems.
Two major groups of copepods, harpacticoids and cyclopoids, both work well for these purposes in aquaria. However, the former work best as scavengers and the latter work best as a zooplanktonic live food. Even within each of these groups, different individual species work best as specific types of cleaners, food items, etc. Thus, a well-balanced community of “pods” seems to be ideal. Maintaining a large, diverse community of copepods is possible with (1) the availability of safe space within a refugium and (2) the regular, generous feedings of wholesome phytoplankton.
In this section, you will learn which species are best additions to your pod community as well as how to maximally boost pod productivity by installing refugia and feeding phyto.
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 …
An Overview of the Firefishes
Marine aquarists are blessed with a gigantic selection of beautiful fish species to keep. Among these, only some are peaceful, reef-safe and relatively easy for beginners to keep. Even fewer are small enough at full size to be suited for nano aquaria. The firefishes are exceptional in that they hit all of these marks. Still, …
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, …
Why Larval Pods are Better for Seeding (Even If You Can’t See Them)
Copepods (pods) are essentially required for any reef aquarium. They perform three important ecological tasks: (1) Graze on benthic microalgae, (2) scavenge detritus, and (3) serve as food for diverse zooplanktivores. They are so ubiquitous in nature, and even in captivity, that they commonly invade new tanks as hitchhikers on live rock, corals, etc. While …

When to Choose Poseidon’s Feast
Back in “the day,” to acquire a seed culture of copepods, aquarists would typically have to resort to scooping a couple cups of gravel from the bottom of a fellow aquarist’s tank. In these cases, you could only hope to have nabbed a few viable pods–and not any pests (like juvenile aiptasia anemones)! If you …
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 …

Why EcoPods are the Best Live Copepod Product Ever
Earth is a planet of pods. Wherever there is water, there are amphipods, isopods, branchiopods, and so on. Pods are an integral part of pretty much every freshwater, brackish and marine ecosystem. But even among all these big players, the tiny copepod is a giant; in terms of both biomass and sheer number, copepods (subclass …

A Look at the Banded Pipefish
So many marine aquarium fishes can be exciting to watch; some are big and belligerent, some are beefy and bullish, some are lightning fast, some are deadly venomous and others are armed with sharp teeth or spines. Even many of the fish we keep in the conventional reef tank can be downright predatory or aggressive, …

Oithona: A Keystone Aquarium Copepod Species
In terms of both numbers and biomass, the copepods (Subclass Copepoda) dominate the zooplankton oceanwide. These minute crustaceans are of immense value ecologically because they play a central role in the linear trophic transfer of nutrients and food energy as intermediaries between primary producers (e.g. phytoplankton) and higher animals such as fish. But it’s usually …
Copepoda: The Ocean’s Cornucopia
In 1905, an engineering mishap caused the Colorado River to flood a shallow basin over the San Andreas Fault in California. With evaporation rates that exceeded rates of inflow, the massive lake began to increase in salinity; Salton Lake was born. Soon, this artificially (and indeed accidentally) made inland sea would develop its own rich …
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 …
Copepods
Imagine for a second how food energy from grass, a primary producer, is transferred to a bluebird. The bluebirds don’t eat grass. Rather, they consume grasshoppers—which certainly do eat grass. In this way every secondary consumer obtains life-giving energy and biomass from primary producers through an intermediate, primary consumer. So it is across the ocean, …
Tig Pods: A Food for Many
The reef aquarium hobby continues to reach new heights. This is most evident by the extraordinarily beautiful systems we see on display in public places, in images on social media, in advertisements, and even in some homes. These advancements have come about not only through improved technologies and supplements, but also through a better understanding …
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 …
Amphipods and/or Copepods: Can They Peacefully Coexist?
Detritus and algal films compromise the aesthetic appearance and environmental quality of any saltwater aquarium. For sure, they present some of the most serious (and frustrating) issues for an aquarist to contend with. The easiest and least expensive way to deal with these issues is through biological control. This typically involves the use of a …

The Refugium: A Home for Your Pods
It just isn’t enough to say that a refugium is “a tank on a tank” or “a sump with some macroalgae in it.” When used to their full potential, refugia make for a far more dynamic—yet more stable—captive ecosystem. Though they are typically smaller in size than the main tank, refugia play a major role …
From Detritus to Delicacy: Using Harpacticoid Copepods for Natural Nutrient Cycling
Pretty much nobody wants their marine aquarium to be covered with filth and green slime. Yet, mulm and benthic microalgae show up (at least in some amount) in just about every system. This is normal to some degree. However, anything more than a patch here or there can be seen as a symptom of problems …
