There is more then one way to skin a cat. In the reef keeping hobby this adage is axiomatic. Given that every single tank is slightly different from any other in methodology used, in how each develops biologically, chemically, and physically, that adage is an extreme understatement. There are general groups of methodologies and philosophies that hobbyists do follow, however, and these can be used to categorize the ‘type’ of aquarium they strive to keep. One of these groupings deals with the type of substrate arrangement hobbyists use in their systems, and there are 3 main categories or methods. Each method is designed to accomplish, or not, what the aquarium keeping community indicates they can, or cannot do best based both on scientific knowledge and anecdotal experience.

Water changes are key to a sucessful reef tank

Posted May 10th, 2007 by Ryan

The most time consuming and least pleasurable task that needs to be done is a water change. There has been much debate as to whether water changes are necessary or not, as well as how often and how much should be changed. After much discussion, the general consensus is that doing regular water changes is crucial to the long-term success of every reef tank. It allows for detritus (and other large pieces of material) and undesirable compounds to be removed from the tank. It is important to do regular water changes because, despite advances in filtration methods, harmful compounds still tend to accumulate in a tank over time. Removing them in bulk during a water change puts less pressure on the live rock and filtration system to break them down. As a result, nitrate and phosphate should not accumulate as quickly.

I did like to order from Live Aquaria. Live aquaria is run by Drs. Foster and Smith. They have good customer service and usually top quality products. However as I was looking down the shipping charges and they are getting ridiculous. Basically Live Aquaria has two locations, one is their main faculty and headquarters which is located in Wisconsin. The other is located in Los Angeles which is where they ship all of their corals and inverts from except if they are from the divers den or aquacultured division.

With that background, if you order lets say a Blue Linkia Starfish and a piece of their aquacultured coral you are going to be charged $34.99 to ship the Blue Linkia Starfish, and an additional $14.99 charge to ship the aquacultured coral. So in effect they are penalizing you for trying to save the wild reefs, charging you an additional $14.99 fee to ship.

Granted I do understand the cost of shipping, including overnight shipping with Fedex. My point is that the $14.99 fee was free, they knew they made a poor logistical decision in building their aquacultured facility in Wisconsin. It would make more sense to build in costly California, right by their Los Angeles Faculty.

I called and complained about this charge to Live Aquaria directly. The manager whom I talked to told me that she would waive the $14.99 charge this once, but it would be charged if I ordered again. That pretty much sums up the fact that I really do doubt Live Aquaria cares about saving the reefs. It would make much more sense to build your aquacultured faculty in Los Angeles then in Wisconsin, charging one fee for shipping.

When setting up a salt water aquarium, one of the most efficient ways of filtration is the addition of a refugium. Not only does it help remove nutrients out of the water, but also serves as a sanctuary for micro-organisms to flourish and reproduce. Also the addition of a DSB (Deep Sand Bed) in a refugium helps serve as a de-nitrifying base for your aquarium. These small sanctuaries for small micro-fauna, copepods, mini brittle stars, and many other small organisms also provide a live food source for your tank inhabitants. There are too many benefits to your salt water aquarium with the addition of a refugium, which should never be passed up. Hopefully this short article can give the hobbyist a better understanding of how beneficial a refugium can be.

One of the most important qualities of a refugium is the exportation of nutrients out of the tank. What are nutrients and how are they exported? Nutrients are also known as Nitrates and Phosphates. Anyone who is familiar with these nutrients and how destructive they can be to an aquarium knows the importance of removing them from your system. Plant life, also known as Macro-algae, will dissolve nitrates and phosphates in your water column. It uses these nutrients to grow and thrive, and most macro algae will grow at an astonishing rate. Once the macro algae has overtaken the entire refuge, simply prune it and watch it grow and dissolve more nutrients. One of the most popular macro algae on the market today is known as Chaetomorpha. Chaetomorpha grows very fast, will not attach itself to anything, and most importantly will not go asexual. When a macro algae goes asexual, basically it is dying and releasing all the nutrients it has dissolved over time back in to the water. This can be very fatal to your livestock, and is why I would highly recommend Chaetomorpha algae. This is by far the best addition any aquarist can add to his or her refugium.

Another great benefit that comes out of a refugium is the various micro-fauna and other critters that will reproduce within the macro-algae, sand and live rock. These critters are good for a few reasons, but most importantly they are great scavengers. Copepods, mysis shrimp, mini-brittle stars, and bristle worms are very small, and can fit into the small holes and areas where snails and hermit crabs. Having a refugium will help maintain or even increase the population of these small organisms in your main tank. Also having a larger population of these organisms in your main tank also adds additional live food for your livestock. Fish, shrimp, hermit crabs, snails and even corals will take advantage of this live food. Not only is live food more nutritional than processed food, it also gives a more natural environment to your livestock.

Overall, the addition of a refugium to any marine aquarium is extremely beneficial, with no ill side effects. They are a great way to help reduce nitrates and phosphates, as well as creating a sanctuary for microorganisms and other little detritus eaters. These organisms usually find a way into your main tank, adding live food for your livestock. A refugium is something that should absolutely not be passed up when setting up a salt water aquarium.

On Jan. 15, 1999, the National Marine Fisheries Service (NMFS) requested comment on the possible listing of elkhorn and staghorn corals as candidates for protection under the Endangered Species Act (ESA). NMFS was considering listing the corals because their populations have been greatly reduced throughout the Caribbean range. Populations declined during the 1980s by up to 96 percent, according to the Federal Register notice. NMFS requested information that would either support or argue against inclusion of these coral species on the candidate list.

Coral-list participants, which generally were equally divided on the issue, discussed the pros and cons of possible ESA protection for the corals, as well as the legal nuances of the act.

The final participant summed up the lengthy discussion by examining the nature of the debate and the conflict between “reductionist” research and “holistic” research.

(Note: NMFS did list elkhorn and staghorn coral as candidates for ESA protection in 1999.)

Yes to ESA Protection

Participants in favor of listing the corals under the ESA generally agreed that such an action would be beneficial. Most agreed that taking an ecosystem approach to species protection would be more appropriate, but such an approach currently is not politically feasible. Therefore, scientists should use the legal tools they do have at their disposal, according to several participants.

In addition, listing would create an “umbrella” of protection that would positively affect the entire system and provide an additional layer of protection over existing habitats. Species that share habitat with the identified corals would reap the benefits of protection as well, participants stated. Though application of the ESA is unlikely to improve current water conditions and habitats, it could help to prevent further decline, according to one participant. However, several participants who favored listing cautioned that it would not be a “panacea.”

No to ESA Protection

Several participants believed that ESA protection was not the best approach. One participant detailed several reasons for his opinion. First, state and federal statutes already prohibit coral harvesting. Corals also are protected within national parks such as Biscayne and Dry Tortugas. With such legal protections already in place, ESA protection would be redundant, according to the participant.

In addition, it would be time-consuming and costly to prove that the corals are threatened or at risk, and the results probably would not satisfy the strict ESA requirements, the participant stated. Research indicates that coral populations are dynamic and experience frequent and periodic booms and busts—a characteristic that may hinder efforts to prove the corals are declining irrevocably. Moreover, damaging natural events such as hurricanes, bleaching and global warming trends will still affect corals regardless of legal protections, the participant stated.

Another participant echoed this sentiment and questioned whether the current data indicates a significant decline. Some coral locations are declining dramatically, but others appear to be healthy, and reproductive capacity has not been shown to be declining, according to the participant. Numerous adequate legal protections are already in place. In addition, ESA protection is only binding in U.S. waters and would not affect other threatened Caribbean coral stands, the participant concluded.

The Legal Arena

Some participants also debated the legal nuances of the ESA. Though some questioned whether the data on the corals was complete and substantial enough to merit ESA protection, one participant with a legal background discussed the act’s requirements and indicated that the corals may indeed qualify despite the uncertainty of their global health.

For example, under the ESA, a species need not be threatened globally to be considered for protection. Rather, it need only be threatened throughout a portion of its range. In addition, application of the act relies solely on the “best scientific and commercial data available.” A species may qualify for ESA protection if data indicate that it is facing present or possible future destruction or modification of its habitat; experiencing overuse of its habitat for commercial, recreational, scientific or educational purposes; threatened by disease or predation; or jeopardized by other human or natural factors that would affect its continued existence.

The participant concluded by cautioning that the legal arena is constantly changing, and certain questions regarding application of ESA remain untested until they appear in court.

Corals will Drain your Pocket Book (humor)

With anything, setting a budget will aid you in this hobby. This is especially true in selecting corals. Corals will eat your wallet up for lunch, and maybe dinner too, to understand why corals are so good at eating your wallet up we need to understand the basic concept of corals: corals are collected from the ocean and then either sold or fragged from a mother colony. A typical one inch frag will run you $40.
