The two most hated things for a saltwater aquarium keeper are fish diseases and “bad” algae. Some hobbyists make an attempt to go all out against these threats by using an ultraviolet sterilizer. At least in some cases, a properly sized and properly installed sterilizer unit can indeed help to reduce the incidence of disease …
Nuisance Algae Control
Without microalgae–phytoplankton, most specifically–our planet could not ecologically function as we know it. Macroalgae too (e.g. kelps) play an enormous role in supporting fisheries, maintaining coastal water quality, etc.
That all being said, there are some bad types of algae. Of course, talk of any organism in Nature as being “bad” requires some sort of clear, objective qualification. One qualifier here could certainly be its negative effect on biodiversity–in cases of uncontrolled population growth. Given that a single turf- or film-forming alga can blanket coral reefs to the exclusion of potentially thousands of other species, they are quite bad indeed.
When we consider that they easily can (and often do) wreak the very same sort of havoc on marine aquaria, the term “nuisance algae” might seem a huge understatement. Let’s face it, these algae are for the majority of aquarists THE single most frustrating aspect of keeping a reef tank. Worst part of this is, you cannot expect to buy any one chemical or piece of equipment and hope to eliminate the problem forever. Rather, you must continuously maintain control over it. You might even have to change your strategy as new types emerge.
In coral reefs (and healthy reef aquaria), these nuisance types of algae are kept in check simply by starvation, as these environments are typically quite oligotrophic (i.e. nutrient-poor). That is, even though plenty of light and carbon dioxide may be available, poor availability of fertilizer (mainly nitrate and phosphate) severely limits their productivity. What little does grow is quickly consumed by herbivores.
In this section, you will learn how to suppress turf- and film-forming algae growth via competing phytoplankton and macroalgae, as well as by removal via clean-up crew animals.
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 …

Correcting Nutrient Instability
Oh, the paradox of algae. They have ruined many tanks–even caused some frustrated aquarists to leave the hobby forever. Yet, our tanks (especially reef tanks) cannot thrive without them–think zooxanthellae. Getting that perfect balance of nutrients, principally nitrate and phosphate, can be exceedingly difficult to ever attain, much less maintain. Part of this challenge lies …
The Cerith Snail: A “Must-Have” Cleaner
Most aquarists are already aware that snails eat algae. To be most correct, the majority of snail species are algivores. To be sure, some have extremely specialized diets that do not include algae; other snails are technically omnivores, eating all sorts of things including algae. Then, for marine aquarists in particular, there is the issue …
Sea Urchins in the Reef Aquarium
My first sight of a real, live sea urchin was in an aquarium (a friend’s) rather than in the sea. This was in my youth (i.e. quite a long time ago) in the upper Midwest–a time and place when/where marine aquarium livestock was quite difficult to get your hands on. Back then, and especially there, …
Chaeto for Major Tank Cleaning
Whether from a lack of experience, or an abundance of neglect, some aquarists allow their reef tanks to reach a state of utter nastiness. Perhaps you’ve been there yourself… Where you once had a gorgeous, natural looking, sparkly clean system, there are now patches of filamentous and film algae, piles of detritus, clouds of suspended …
Understanding the Nitrogen Cycle
We are finally starting to see a surge of interest in the nitrogen cycle & the “aquarium microbiome.” That is a very, very good thing, not just because understanding the microbial workings of our captive ecosystems is critical to our success as aquarists, but also because we remain woefully uninformed about (even unaware of) the …
The Whole Package: Integrating AlgaeBarn’s Kits & Combos
AlgaeBarn is hardly the only aquarium hobby-centered business to produce phytoplankton and macroalgae. But we like to think that we’re pretty darn good at it–if not the best! Consider our highly-acclaimed premium live phyto blend OceanMagik in various kits or our standard-setting CleanMacro series. If it needs to be stated, algae is kind of the …

How to Control Hair Algae
Hair Algae Happens Algae Happens. Even the types that we don’t want in our aquaria–and actively try to eradicate (like hair algae)–can gain a pretty good foothold from time to time. This isn’t necessarily the worst thing that can happen… After all, every “bad” algae species occurs naturally in the wild and serves some important …
Bubble Algae: How Bad Is It?
Every reef tank has some form of hardscape–a reef base. Unless they are obtained dry, these materials almost always have some form of algae on them, even bubble algae. And even if dry rock is used, tiny bits of algae can slip into the tank later by way of coral skeletons, frag plugs, etc. While …
4 Pitfalls for the Beginning Reef Aquarist (And Some Experienced Ones, Too)
If you’re reading this, you probably love marinelife. And if you don’t already have an aquarium (or two), you’re itching to fix that problem soon. We get your enthusiasm. Like any hobby, aquarium keeping is a highly enjoyable pastime. But it’s not all fun and games. Successfully maintaining an aquarium, especially a reef tank, requires …

Unique Algae Eaters for your Aquarium
Even though battling algae is best done by finding and solving the underlying nutrient or lighting issue, it certainly doesn’t hurt to have a few algae eaters in your tank to help keep it in check. Home aquariums naturally have more nutrients than wild ecosystems, and the slightest change in maintenance can lead to short …
Dealing with Cyanobacteria
In my time working at a local fish store, I have come to realize that hobbyists that have been keeping saltwater tanks for years often run into similar problems as new hobbyists. But, most of newcomers’ algae problems are simply due to their tank naturally cycling, and they resolve themselves within a month or two …
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, …
Utilizing the Trochus Snail (Trochus spp.)
Algae, of course, is not an inherently bad thing; without it, the natural world could not exist as we know it. However, there are many types of algae that readily grow in plague proportions under certain environmental conditions. Imbalances of nutrient levels (whether in nature or in the home aquarium) can quickly result in blooms …
Eliminating Nuisance Dinoflagellates with Ocean Magik Live Phytoplankton
Eliminating harmful and ugly dinoflagellates remains 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 animal deaths, chemical water treatments/medications, increases of …
