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
Phytoplankton
The first link in a food chain is always a primary producer (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 substances such …
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. 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, are predictably delivered to the reef from adjacent, comparatively fertile open …
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 …

Stocking a Refugium
Marine aquaria have a peculiar way of growing (in terms of both size and complexity) over time. These “add-ons,” be they filtration units, reactors, or whatever, grow from the so-called main tank in an almost organic manner. But, no matter how elaborate an aquarium set-up becomes, the sum of all the parts can always be …
Pods In Your Reef: Seeding a Marine Aquarium with Copepods
Benefits of Pods In Your Reef: Microcrustaceans (or “pods”) in general, and copepods in particular, are an integral component of aquatic food webs. This is so in virtually every marine environment including coral reef habitats. Therefore, pods in your reef are a healthful addition to any reef aquarium. Lucky, a handful of useful copepod species …

Mandarin Goby Fish Care | Using Copepods to keep a Mandarin Dragonet
Mandarin Goby Fish Care 101: Foods and feeding are the foremost concern for any aquarist wishing to keep a green mandarin fish (Synchiropus splendidus). Most critical in the diet of a mandarin is (1) constant availability of feeding opportunities and (2) food sources that are varied but primarily consist of enriched pods. If you get …

Isochrysis: The Microalgal Reef Aquarium Superfood
A golden marine phytoflagellate, Isochrysis (sometimes referred to by aquarists simply as “Iso”) is classified as: Prymnesiophyta (Phylum); Prymnesiophyceae (Class); Isochrysidales (Order); Isochrysidaceae (Family); Isochrysis (Genus). The genus is comprised of marine, free-living, unicellular flagellate haptophytes.
Getting Your Greens: The Benefits of Feeding Live Nannochloropsis
Most of us want—and should want—our aquarium systems to more or less function ecologically in a way that resembles natural marine environments. Probably the most critical aspect of this is establishing a naturalistic food web. Unicellular, free-living, perpetually suspended algae (i.e. phytoplankton) account for a great deal of primary productivity in areas over or close …

Feeding Your Hungry Pods
Marine aquarists are really attempting to accomplish several goals when introducing copepods to their systems. These undoubtedly include elimination of detritus, controlling nuisance algae and providing excellent nutrition for countless reef fish and invertebrate species. But the general aim, of course, is to create a more dynamic and balanced captive ecosystem. After all, copepods are …
Fats, Phytoplankton and Aquarium Animal Health
We are often (and should be) concerned about how much food some of our more finicky or delicate aquarium animals are eating—or if they are eating at all. Too often, however, inadequate attention is paid to food quality. Without doubt, diet has an enormous impact on the health, appearance and even behavior of our marine …
Mixed Microalgal Feeds for a Balanced Nutrition
Primary producers—those organisms (e.g. plants such as algae) that build new biomass from inorganic sources of energy—form the very base of all food chains. They are of most obvious importance to herbivores. But, of course, without producing the material upon which herbivores feed, nothing else down the chain could exist. And the dependence of carnivores …
Keeping and Feeding the Sun Corals
Reef aquarium keepers are always looking for that one oddball “piece” of coral that will really make their aquarium display shine. Sometimes this is just something a little different in terms of ecology or behavior. Other times it is something that is atypical in terms of shape or placement. Quite often it is something that …
Carnation Corals in the Home Aquarium: A New Hope of Success?
Advancements in the reef aquarium hobby have been developing at a dizzying pace. As our understanding of coral reef biota (and how to care for them in captivity) grows, many more tools are becoming available to those who wish to keep increasingly specialized aquarium systems. As of late, there has been a particularly strong interest …

Eliminating Nuisance Dinoflagellates with Ocean Magik Live Phytoplankton
Maintaining a healthy balance of microalgal species remains as one of the most common—and challenging—tasks for the marine aquarist. Not only can marine aquarium systems be far less chemically stable than the natural reef environment, but they are also subject to disturbances that can occur following bouts of overfeeding, decay associated with …

Choosing the Right Live Phytoplankton Reef Tank Blends
Many common reef aquarium animals are filter-feeding phytoplanktivores. In other words, they eat tiny (usually single-celled) algae that they capture from the aquarium water. In the natural environment, they often eat a lot of it. Despite that, they are in many cases quite choosy about what they eat in terms of food particle …

Aquariums: The New Medicine
You enter the waiting room of your doctor’s office and you know she’s not going to be happy about your blood pressure or weight gain. Your palms start to sweat as you try to think of excuses for your lack of exercise and bad eating habits. As your pulse quickens, you look over to the …
