Today we are going to take a look at cooling fans and aquarium chillers as well as provide you with some helpful tips that will help you beat the heat this summer and keep your water temperature stable.

With summer fast approaching, it is the perfect time to start thinking about your aquarium's water temperature. While aquarium chillers are the best option to maintain stable temperatures in your tank, they are expensive and may only need to be used a few weeks out of year.

Fortunately, for many of us, cooling fans can be a thrifty way to keep our tanks cool. Enclosed canopies and stands are probably the most common situation were a cooling fan can drastically reduce water temperature. Enclosed stands and canopies can trap a substantial amount of heat and by installing a fan, you can pull the hot air out and away from your tank.

Another great way to use a cooling fan is to blow air over the surface of your aquarium water. This will increase water evaporation and in the process will cool down your aquarium water. Up Aqua and Zoo Med aquarium fans are great for smaller tanks, while the stronger JBJ C-Breeze and Tunze Aquawind are great for larger aquariums.

Having an aquarium controller is also a great tool to help keep your tank cool. While the controller will not directly cool your tank, it can turn certain pieces of equipment on or off when temperatures are out of range. For example, you can program the controller to switch your aquarium lights off if your water temperature reaches 80° and turn on a cooling fan at the same time—then resume normal operation when the water temperature drops within suitable ranges.

If you have a more advanced controller like the Neptune Systems Apex AquaController, you can even get an email or text message alert when your temperature starts to rise then remotely control pieces of equipment that cause an increase in temperature to help you get through those hot summer days.

If cooling fans just won’t cut it, then an aquarium chiller is the way to go. Chillers are basically like air conditioners for your aquarium water and will very efficiently lower the water temperature in your tank. We stock a wide range of chillers that are suitable for tanks of all sizes. For nano tanks, the CoolWorks MicroChiller is really cool because you can simply hang it on your tank and no additional pumps or plumbing are required. The Chill Solutions CSXC-1 Inline Thermoelectric Chiller is another great option for nano tanks because it can handle an aquarium up to 30 gallons but is very small compared to other chillers in its class.

For larger tanks, something like the JBJ Arctica or Aqua Euro USA chillers are going to be required. The exact size depends on how much water is in your tank and the desired temperature drop. It is always best to oversize slightly as you do not want your chiller running all the time. A larger chiller will cool the water quicker and not consume as much electricity as a smaller chiller running all the time. These types of chillers are typically installed inline, which means they require some extra plumbing as well as a dedicated pump or water feed line.

Fish and corals are delicate animals. Drastic changes or incorrect temperatures can cause severe stress or even death. By being prepared to combat hot temperatures, you can help ensure that your aquarium inhabitants stay cool and healthy through the long lazy days of summer.

We appreciate you tuning in and helping to keep our hobby alive and thriving! Until next time... take care and happy reefkeeping.
