In the previous installments we talked about skeptical methodology and how it can be used to sort through the overwhelming amount of reefkeeping information that is now at the virtual fingertips of reef hobbyists. We also discussed how skeptical thinking has impacted the idea of sustainable reefkeeping, scientific terminology, magic products and more. In this installment we’ll take a look how to decide which expert to listen to and the most important tool in the skeptical reefkeepers toolbox.

A brief reminder to set the scene

Skepticism is a method, not a position. Officially, it’s defined as a method of intellectual caution and suspended judgment. A skeptic is not closed minded to new ideas, but is cautious of ideas that are presented without much, or any, supporting evidence. In our hobby there are tons of ideas presented without much, or any, supporting evidence. Being a skeptical reefer essentially boils down to taking advice/products/new ideas with a bucket of salt. Being a skeptical reefkeeper requires that you investigate why, how and if the suggested ideas actually work. As a skeptical reefkeeper, you decide what is best for you, your animals, and your wallet based upon critical thinking: not just because you heard someone else say it. The goal of this series of articles is not to provide you with reef recipes or to tell you which ideas are flat out wrong or which products really do what they say they do or which claims or which expert to believe – the goal is to help you make those kinds of determinations for yourself while developing your saltwater thumb in the face of sometimes overwhelming conflicting advice.

Experts

In any endeavor, it is always great to be able to consult with someone who has more experience than you do. There is no need to reinvent the wheel, and avoiding avoidable mistakes can save you time and money, as well as lives of animals. However, there are ‘experts’ everywhere you turn, and it can be difficult to know who’s expert advice is worth listening to and who is just spouting opinion or perpetuating something they heard somewhere under the guise of being an expert.

We also discussed how skeptical thinking has impacted the idea of sustainable reefkeeping. In this installment we’ll take a look at some of the terminology that is used in reefkeeping and see if the terms make sense or are misleading (potentially, accidentally, or purposefully).

Words words words

This is a photo of and elephant seal and has nothing to do with this article.

Our hobby is constantly evolving, and the terms we use to communicate ideas to one another change and morph over time and these changes can lead to confusion. For instance, the term refugium initially referred to an area of a system that small animals could use as a refuge from predation, but now refugium also refers to an area of the system used to grow algae for nutrient export or simply a small tank plumbed into a larger system. The ideas can overlap, but they don’t necessarily, so when someone asks for information on setting up a ‘fuge, it becomes important to know what the term means to them in order to help them with information relevant to their needs.

In the previous two installments of Skeptical Reefkeeping, we talked about how applying skeptical thinking to reefkeeping can help you make decisions about what methodology to follow or which products to use. In this installment, we’ll spend less time exploring the skeptical method, and instead examine how skeptical reefkeeping has impacted, and continues to impact one particular aspect of our hobby: making our hobby more environmentally sustainable.

That sounds like work! Just tell me what to do!

Sorry, I can’t just tell you what to do. I wish I could, but there is that whole Biblical quote “Tell someone what to do and their fish and corals die, get them to understand the bigger complex picture and their fish and corals live”. This hobby is not simple and there are as many opinions about how to keep our glass boxes thriving as there are people with glass boxes. The goal of this series of articles is not to necessarily provide you with reef recipes or to tell you which ideas are flat out wrong or which products really do what they say they do or which claims or which expert to believe – the goal is to help you make those kinds of determinations for yourself in the face of conflicting advice.

The drama of ‘juicing’ fish

The early 80’s was a time of glam rock, hardy elegance corals, and DIY sumps filled with hair curlers for bio media. Back then, rocks covered with hair algae were lovely, panther groupers were the hot fish, and aiptasia were considered fabu. Hardly anyone stopped to think about where animals for our reef tanks were coming from…we were all too busy just trying to keep them alive for more than a month. Fish would come into the LFS; some would make it, and some would slowly waste away despite eating well. Most of us figured we were making some husbandry mistake that resulted in the death of the fish. However, some began to apply skeptical methodology to the problem and hypothesized that the issue might have something to do with the way the fish were being handled somewhere along the way to the LFS.

Cyanide fishing kills fish and corals – which hardly seems to justify the lower prices the practice can create.

It turned out that they were right. Investigation revealed that cyanide, often called ‘juice’ was used to ‘knock out’ fish to make them easier to collect. Sounds good right? Easier to collect means cheaper, cooler animals, and everyone wants cheaper animals. However, the monkey wrench here is that cyanide is a poison that doesn’t necessarily kill the fish outright. Often, the fish seems to recover from the initial shock. It can make it all the way through the chain of custody from the collector to the exporter to the importer to the LFS to the hobbyist tank before it begins to go down hill. We now know that the cyanide can damage the fish’s ability to adsorb food; it can eat like a pig, but get little of the nutrition it needs to live. Eventually, the animal can starve to death. More »

…or this?

In the last installment we talked about the role anecdotal evidence and logical misunderstandings play in how we make decisions about reefkeeping. In this installment, we’ll look at how and why manufacturers make claims about their products, why you might want to be skeptical about them, as well as some practical advice for determining the validity of those claims.It seems you can’t turn around in the reefkeeping world without bumping into another new product that you must have to keep your reef healthy. The claims are usually the same, always some version of one of these:-This product will unlock your reefs potential.
-Cure any and all disease in a reef environment.
-This will change the way you keep your reef.
-You’ll see colors and animal health that you have never before experienced.
And my personal favorite:-YOU’LL NEVER HAVE TO DO REGULAR MAINTENANCE ON YOUR TANK AGAIN!The ads are very clear in a roundabout way; Without THIS product your reef sucks.

Honestly, sometimes a new product does work. A lot of them don’t.
Even widely used products occasionally don’t do what they claim but in spite of this, somehow they’ve caught on.

I’m going to tell you the one thing you can learn to do for your reef that will improve it’s condition, and your sanity, from day one: Skeptical Thinking.

What is Skeptical Thinking, Rich?

I’m glad you asked. First, it’s not being a grump. For some people the idea of being a “skeptic” has a negative connotation, but do Shaggy and Scooby Do seem like grumps? They’re skeptics. Think about their show. At the end there never is a monster or a ghost, it’s always, as Tim Minchin would say, “the dude who runs the water slide.” More »

Reefkeeping is as much an art as it is a science. There is so much that we don’t understand about what actually goes on inside our boxes of water that we must rely on cultivating a ‘saltwater thumb’ for success over time. Building that saltwater thumb, however, can be a daunting task. There are a million opinions on every aspect of reef keeping, and the modern reefkeeper can access those opinions thru websites, online forums, or those big heavy things on the shelves at home (Books? I think that’s what they’re called). Essentially, you can find support for every aspect of the hobby regardless of how ‘fringe’ it may be – the question is, how do you sift through all those opinions to make decisions about what to do with your reef tank? My answer – be a skeptic. In the next few issues of Reefs Magazine, we’ll look at critical and skeptical thinking, how they relate to reefkeeping, and how they can help you wade through the flood of good and bad information available to the modern reefkeeper.

Be a Skeptic

The idea of being a skeptic seems to have a negative connotation, as if somehow being skeptical means saying no for the sake of saying no. That’s not quite right. Skepticism is a method, not a position. Officially, it’s defined as “a method of intellectual caution and suspended judgment.” A skeptic is not closed minded to new ideas, but is cautious of ideas that are presented without much, or any, supporting evidence. In our hobby there are tons of ideas presented without much supporting evidence. Being a skeptical reefer essentially boils down to taking advice/products/new ideas with a bucket of salt, and following up to get a handle on why, how and if the suggested ideas actually work. This boils down to the one adage about reefkeeping that almost every experienced reefer agrees with, namely, be patient. Taking your time in your decision making is just as important as taking your time stocking your reef because, as they say, “nothing good happens quickly in a reef tank”. So, when that shiny new idea about reefkeeping shows up, with many people being very excited – slow down and think. More »
