Fresh tank tips from the algaebarn blog
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 …

Water Flow in the Refugium
When it comes to setting up your refugium, there are plenty of considerations to make. You must select macroalgae species, clean-up crew species, a type of substrate (or none?), lighting and so on. Most of this planning is pretty fun. But, with so much to think about, and so many options, it might be easy …
A Beginner’s Guide to Setting up a Refugium
By Nathan Peel There are many benefits to building or creating a refugium in your saltwater aquarium. It allows for additional surface area for beneficial bacteria to grow, which filters out nitrates and nutrients in an efficient and natural way. They also provide a habitat for small beneficial organisms so they can reproduce without getting …
Increasing the Efficiency of Your Sump to Decrease Water Changes
Water changes are the most dreaded part of regular tank maintenance to most hobbyists. So much so, that many people start skipping water changes for weeks or months at a time. I don’t blame them, lugging buckets, checking salinity and parameters of new saltwater, stressing fish and other tank inhabitants, and the inevitably of spills …

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 …
Lighting the Refugium
There are plenty of reasons that you might consider installing a refugium in your marine aquarium system. Yours might be to add water volume to compensate for an increasingly crowded main tank. You might want to boost your copepod production. Most probably, you’re aiming to reduce dissolved nutrient concentrations. Particularly in the latter case, you’ll …
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 …

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 …
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 …
MarinePure: The Ultimate Biomedium
MarinePure: The Ultimate Biomedium Managing dissolved waste products might easily be the most important—and oftentimes most challenging—task for a marine aquarist. Ammonia, nitrite and nitrate are the waste products that usually dwell at the forefront of the aquarist’s mind, as they should be. Ammonia and nitrite are, of course, extremely toxic and can wipe out an …
Feeding Your Marine Animals Live Macroalgae
Farmed in the ‘Fuge: Feeding Your Marine Animals Live Macroalgae Grazing might appear to be an easy and carefree way for an animal to get its meal. This is, however, not often so. For one, plants have comparatively less protein and fat content than meaty fares. Herbivores therefore must consume considerable amounts of food to …
Ulva spp. Seaweeds: The Refugium Powerhouses
Virtually all marine aquaria have fish residing in them. And fish must be fed. Which is fine, because most hobbyists enjoy feeding their animals and do so quite generously. The result, however, is a whole lot of fish waste. These waste products are mineralized (that is, broken down) through biological processes into simple compounds such …
Aquarium Cleaning Machines: Cerith Snails in the Reef Tank
An aquarium substrate surface can be a dirty place. Detritus, feces, uneaten fish food, film algae and other unwanted materials might pile up there. Fortunately, there are many “clean-up crew” creatures that can be used to remove various types of nuisance algae and/or settled organic wastes. There are only a few cleaners, however, that will …

An Overview of the Green Alga Chaetomorpha
The typical purpose of a refugium is to cultivate a thick bed of macroalgae. While some refugium plants like chaetomorpha provide important habitat for microcrustaceans (e.g. pods) and may even be considered to be ornamental, they are used primarily to take up excess nutrients (e.g. nitrate, phosphate) from the aquarium water. In practice, these nutrients …
An Overview of the Red Alga Gracilaria
There are a lot of good reasons to incorporate a planted refugium with Gracilaria into one’s marine aquarium system. The usual stated purpose is for the removal of excess nutrients such as nitrate and phosphate that build up in the aquarium water. In theory, these nutrients actually exit the system when algal biomass is harvested …
Going Green: Installing and Operating a Planted Refugium Sump
Many aquarists strive to build and maintain aquarium systems that replicate, as faithfully as possible, the natural environments from which their collection of animals originates. This is certainly not without some considerable reward, as doing so not only results in a more interesting captive ecosystem, but also promotes these creatures’ health, fecundity …

Sustainable Aquariums
What are Sustainable Aquariums? An aquarium is a cornerstone of many homes and apartments, but how often have you come home to find your fish floating belly up? Whether the kids forgot to feed them or neglected to change the water filter, the bottom line is it’s time to go out and get a few …
