A recent shot of Paul B’s 40+ year old reef aquariumMany marine fish can survive in captivity for decades, and many corals and other sessile invertebrates can hang in there, well, who knows how long. In any case, maintaining a marine aquarium “for the long term” can mean an awfully long time. Just ask Paul B, author of The Avant Garde Marine Aquarist. His current tank has been up and running with much of the same livestock since somewhere around the Second Battle of Bull Run (being a New Yorker, Paul presumably wouldn’t have called it Second Manassas). My style of aquarium keeping also leans toward the long-term, so I thought I’d dedicate today’s post to what I consider the pros and cons of this approach (versus keeping specimens for relatively brief periods and frequently changing up your livestock) for those whose hobby experience doesn’t yet span decades:Pros: You gain a new respect for the growth potential of specimens—and thus the benefits of spacious housing. For example, reading that fish species X can reach Y inches/centimeters in maximum length doesn’t compare to actually seeing the genuine article fully grown and swimming around in your tank alongside a bunch of other fully grown specimens. by ReefBum | Feb 25, 2016 | Equipment, Reef, Science
Over the years, a kalk reactor has always been an integral part of my reef keeping setup. I have used one to dose kalkwasser via my RODI top off to boost pH, which is lowered by my calcium reactor, and to augment my tank’s calcium and alkalinity levels. I did have reliability issues with the one plumbed into my old 225 gallon system so I was on the lookout for a more solid and trustworthy unit for my new 187 gallon setup. I did some homework and eventually settled on a My Reef Creations Nilsen (Kalk) Reactor. These reactors are available in small, medium and large sizes. I went with a medium, which has a footprint of 8-1/2 inches, 12 inches including the pump, and is 19-1/2 inches tall. Essentially, this unit by Saltwater Smarts | Feb 25, 2016 | Equipment, Fish, Reef, Science, Technology
Here’s the FishBit monitor mounted in my 125 gallon reefRegular Saltwater Smarts visitors are well aware that I’m not exactly what you’d call “tech-savvy” or an “early adopter” when it comes to the latest gadgetry (though I am intrigued by this newfangled doohickey the kids call an “eight-track player”—it’s gonna be yuuuge!). So, it should come as no surprise that I take a pretty low-tech approach to the marine aquarium hobby. Nothing in my system is really automated (unless you count the timer on my lights), and I don’t use a lot of devices beyond your basic heater, protein skimmer, and submersible pumps. And, until very recently, I monitored all my water parameters the way God intended—using a hydrometer, floating thermometer, and various and sundry colorimetric test kits.I tell people that I like to keep things natural, but the truth of the matter is, my lone functioning brain cell has always struggled with technology and figuring out how the various components of a high-tech system interconnect (how I managed to finish Air Force Crypto School with high marks back in the day is anybody’s guess!). So, when Nathan Levine, founder of Current Labs, asked me to beta test their new FishBit monitor and controller, I was a bit apprehensive. How embarrassing would it be if I had to admit I couldn’t figure the thing out or, much worse, if I somehow damaged the unit by installing it upside down or…I don’t know…accidentally swallowing it? But after hearing that FishBit is specifically designed to be easy, trouble-free, and intuitive for people like me (analog folks trapped in a digital world), I felt somewhat reassured and agreed to give it a try. FishBit allows you to monitor key water parameters in real time as well as control multiple aquarium devices, such as your lights, pumps, and heater, through an app on your smartphone or other device. by Saltwater Smarts | Feb 15, 2016 | Equipment, Fish, Photography, Reef, Science
Indiscriminately scrubbing live rock can destroy much of the life you paid for, and thus the benefit of doing soQuestionI’ll be receiving a shipment of live rocks in a few days, and I could use some advice on how to clean them up before putting them in my tank. Do I just need to give them a good going over with a scrub brush?” – Submitted by Chuck S. Answer I wouldn’t use the term “good going over” with respect to cleaning your new live rocks. Remember, you paid good money for the organisms encrusting those rocks, so you don’t want to scrub the entire surface of each rock indiscriminately. Rather, what you want to do is very selectively scrub/scrape/pluck away any obviously dead/decomposing organisms, slimy films, unwanted algae, and clinging sediments or debris. Encrusting sponges that have been exposed to air will also need to be removed, as they’re likely to die and decompose. Otherwise, if a rock looks pretty “clean” and healthy right out of the box, all it needs is a good rinse. by Saltwater Smarts | Feb 5, 2016 | Corals, Equipment, Fish, Industry, Photography, Reef, Science, Tanks, Technology
Actinic lighting was developed and used in other industries before reef aquariumsWe marine aquarists use a variety of tools to help keep our tanks healthy by either changing or removing the waste products of the animals we keep. But did you know virtually all of the devices we use were originally designed for other industries? OzoneFor instance, ozone is a naturally forming gas found in our atmosphere that helps protect us from the damaging effects of the sun’s ultraviolet radiation. It was discovered in 1839 by Christian Friedrich Schönbein. Ozone was originally used to purify drinking water and as a health-giving gas. Unfortunately, that health idea produced just the opposite result because the oxidizing effect we can use to purify certain things will also oxidize us, especially our lungs.
