We love aquarium related workshops, whether they be some sort of husbandry demo, a product showcase, or anything that spreads the good word of the hobby. We especially love them when the events are local. Such is the case for a Red Sea workshop that will be hosted at one of our favorite Houston area fish stores, FJW Aquarium. The event is still a little ways away, being hosted on September 20th from noon to 4pm. Like many events, this workshop will also feature awesome deals on livestock and equipment, as well as raffle prizes and other attractions that will bring in local hobbyists in droves. As we said, the workshop will take place at FJW Aquarium, located at 3839 Mangum Road in Houston, Texas. More details about the event will unfold on the FJW Facebook announcement, linked to above. A representative, or representatives, from Red Sea will be in-house doling out the goods on all of their latest gear, presenting a great opportunity for users to become more familiar with their dosing systems and other popular products. by AquaNerd | Aug 6, 2014 | Fish, Science, Tanks
Gracing the AquaNerd Picture of the Week this time around is the beautiful, yet not so reef friendly, Pakistan butterflyfish (Chaetodon collare). While we don’t have any personal experience with this fish, we have crossed its path several times at public aquariums all over the globe. It is a beautiful fish, no doubt, but its diet of SPS polyps and notoriously finicky nature make it a surprising choice for most public exhibits. In all of the displays we’ve seen the fish, none were in Acropora-ridden tanks, which means the caretakers must be providing them with superb attention and the perfect diet. The butterfly is known for its dark body that is highlighted with lighter colored scales. It’s boldly colored red tail and stand out sharply against the darker background, as does the fish’s vertical white stripes on its face. by AquaNerd | Jul 30, 2014 | Fish, Science
Apparently, there’s such a thing as fish shaming. In this interesting act of internet virality, an aquarium owner posts conceivably embarrassing messages about their fish. While the comedy of humiliating fish on the internet may be lost on some (or likely most) people out there, believe me when I say that it’s the perfect message for an aquarium keeper. In the images shown above and below, which were taken from the Tumblr page Distinct Memory, the fish were apparently overly aggressive toward tankmates, inflicting some sort of damage or death that the aquarist was tired of. The hobbyist then used the power of social media to let the world know of the fish’s bad behavior. And while the fish obviously aren’t really even aware of what’s going on, we got quite a chuckle from this fish shaming and would love to see it expanded towared more of our salty pets as well. Just image, shaming that “reef safe” angelfish for nipping at all the clams or humiliating a clownfish for trying to host a water pump. The possibilities are endless. by AquaNerd | Jul 28, 2014 | Equipment, Fish, Industry, Science, Tanks
Innovative Marine is living up to their namesake this week with the announcement of the most well-equipped all-in-one nano aquariums on the market. They are bolstering their Nuvo Fusion lineup, going a little smaller to target those hobbyists who enjoy a beautiful yet insanely functional desktop sized aquarium. The new models will include the Fusion Nano 10 and 20, and despite their size, they will enjoy all of the same features of their larger brethren. That means a 10 and 20 gallon tank with low iron glass (an industry first as far as we know), mesh screen top to keep fish in, built-in overflows, a rubber leveling mat, and some impressive rear chamber filtration. And you know what the real shocker is…the tanks start at just $99. But the fun doesn’t stop there. As IM has done in the past with other aquariums, the lineup has been given access to some really awesome third-party upgrades. by Tami Weiss | Jul 28, 2014 | DIY, Equipment, Fish, Science, Seahorses, Tanks
Summers can be deadly to seahorses. Are you prepared to cool them down? Summer’s here, and seahorse aquarists are starting to see tank temperatures rise. Seahorses, are particularly vulnerable to warmer temperatures , so for many seahorse aquarists, even moderate heat can lead to a mad dash to lower the water temperature. The consequences of warm water can be deadly for seahorses. Bacteria spread at a faster rate in warmer water, so the warmer it gets, the more likely you are to see illness pop up in your aquarium. Another often overlooked problem is that warmer water holds less oxygen, stressing out the inhabitants of your aquarium. This tends to be worse for seahorses than other fish due to their lobed gill structure. Fans, your first line of defense Often, open tops with fans blowing across the water is enough to drop temp a few degrees. This works by evaporative cooling. Removing tops, and placing a fan so it blows across the water will make the water evaporate much faster, cooling the tank. You can easily drop a tank below the ambient temperature if you have enough evaporative cooling. Theoretically, you can drop as much as 18F degrees below ambient temperatures. Realistically, you are going to see a drop of between 3 and 5 degrees in a home aquarium. (More about evaporative cooling here.) Ways to improve evaporative cooling is to have the fan blowing across the longest part of the tank. Aiding evaporation can be done by increasing surface movement. Position power heads and add air pumps to create more movement. If you have a sump, you can help things out by placing a fan across the sump as well. Keeping the stand doors open will help heat from equipment dissipate. Be sure if you have fish that could be jumpers that the tank has some form of mesh over the top to keep them from making their final leap. You can use egg crate to fashion a top, or pond mesh and aluminum window frames. Do remember that with evaporative cooling, you will lose significantly more water through evaporation than normal. Keeping an eye on the tank, or even adding an auto top-off unit to replenish the tank will be necessary. Evaporative cooling works best in dry climates. Someone in Arizona will have better results than someone in Florida. However, if air conditioning is being used, you have a dehumidifier build in, and can get to lower humidity levels to keep the tank cool. Air Conditioning Often when people think cooling a tank, they think they need to resort to a chiller. That’s not always the case! Often times it’s cheaper to get a room air conditioner and run it rather than buying a whole chiller. And for bonus points, you get a cool room. Of course, it depends where you live, where your tank is set up, and what your electricity prices are like. But it’s always a good idea to at least consider air conditioning. Small units can be had for under $100. If you have odd shaped windows you can get a portable air conditioner. Portable air conditioners carry warm air out via a hose that you connect to a window. They do take up floor space, and some people think they’re loud; but they provide an option for those of us with weird windows. Check Your Equipment There are many ways you can change your equipment setup to help remove heat. Reducing equipment, externalizing equipment, and even cleaning equipment can all help. Reduce Equipment If you’re running several powerheads to keep water moving, a pump from the sump to the tank, and a pump for the skimmer, you could easily be dumping a large amount of heat into your aquarium. Reducing those items while keeping the water moving is a great way to lower the temperature of the tank. Multiple powerheads can be replaced with a single, well designed closed loop. Upgrade Equipment Older equipment is likely to draw more power mom less umph. The additional power translates to additional heat in the tank. Newer, low watt pumps can lower the overall energy consumption along with the heat output. Don’t forget the lowly air pump! Most are low watt and can move around a substantial amount of water, even if it’s not in the way we’re used to in an aquarium. But they can work to keep the surface agitated with very little cost or heat addition. Externalize Equipment Every piece of equipment in the tank adds to the heat overload. If you can externalize the pumps that are in your aquarium, you’re reducing a lot of the equipment heat. External sump pumps can be plumbed alongside your sump. Internal powerheads can be upgraded to those with external motors, such as a VorTech (just be sure to use the foam covering to keep seahorse tails out). Clean Equipment Because our tanks are alkaline with a lot of minerals, calcium deposits occur inside our pump housing. This creates friction, and friction is heat. It may sound like a simple step, but cleaning your pumps every couple of months can help keep the temperature in check. A good vinegar soak followed by a thorough rinsing will remove calcium deposits with ease. Chiller A chiller is often the nuclear option in high temperature situations. They are expensive and take up space. And you need to be sure you’ve chosen one that can cool your aquarium to the right temperature. There are many low cost models out there that don’t cool as much as they purport to cool, so checking reviews is essential. Pet Education has a great article on choosing the right chiller Chiller Sizing Calculator DIY Chiller One way to go about a chiller on a budget is to make your own. While they are rarely pretty, they are an option for those on a budget or just like the challenge of building something themselves.Most rely on a dorm fridge which can often be had for next to nothing, and a big coil of aquarium tubing where water passing through, is cooled, and passed back into the aquarium. DIY Chiller ideas: DIY Evaporative ChillerRefrigerator ChillerDIY chillerAnother DIY ChillerDIY ChillingDIY Do It Yourself Aquarium Chiller Basement If you’re in a warm climate and air conditioning or a chiller isn’t an option, but have access to a basement, sometimes the reality is that it might be the best place for your aquarium. Placing in the basement is not something you can do quickly during a heatwave, but if you’re deciding where to set up your aquarium, be sure to think of what the conditions are going to be like throughout the year. Sometimes placement in the basement is just a fact of life. If you have a concrete floor, you can even take advantage of natural cooling by placing the aquarium sump directly on the concrete rather than raising it up to sit on wood inside the stand. It may take some clever modifications, or a custom built stand, but can be well worth the cooling effect of the concrete. Ice in Emergencies Keeping a couple bottles of ice in the freezer can be a lifesaver. They don’t take up much space, but in an emergency such as a/c or power outage in a heat wave, they could make all the difference in the world. The downside is that you don’t have much control over the cooling. But they could end up saving your seahorses. If you don’t have bottles of ice, and need something FAST, regular ice can be used, but place it in a ziplock bag so it doesn’t melt into the tank. You don’t want it diluting the tank, only cooling. Ice Chiller In a prolonged emergency or unexpected heat wave, you can make a temporary chiller out of a cooler, ice, a coil of aquarium tubing (at least 75’) and a pump to push the water through the tubing coiled up in the cooler. A more detailed explanation. Following the above advice should let you cool your seahorse aquarium to safe temperatures with ease, leaving you, and your seahorses to sleep better at night. DIY Ice Air Conditioner You can even make an air conditioner using a number of inexpensive parts if you’re really in a bind. The idea is to have a fan pushing cold air out of a container. The essentials are a small fan, ice, and a container for the ice. Youtube has a couple examples, one using a 5 gallon bucket, and another using a cooler. I suspect neither would last long term, but they might be a good short term solution for cooling a room with aquariums rather than trying to cool each room. And they’re dirt cheap to build.
