We are in the dead of summertime. Across the United States tempatures have really lit up the thermometers. Your aquarium is most likely feeling the effects of the increasing tempatures as well. What are some ways in which that you can cool your tank in the summertime? The most obvious choice would to buy a chiller unit to cool down your tank which would work, but that is an expensive option. Another option would to buy a fan unit of some sort either sump mounted or tank mounted. This is a very popular option for most aquarsts across the globe. Fans are efficeint in cooling your tank down. However with the fan unit you will have increased evporation from your tank. This isn’t a huge problem as most aquarists are willing refill their tanks with more RO/DI water versus having sticker shock of a full blown chiller unit. A typical fan unit will set you back about $45, versus a chiller unit pricing from $700-$3000.
Keeping your AC on while your at work is also another option. Keeping your ambient room temperature at 74 degrees will greatly help in cooling your aquarium. Depending if you have a newer central AC unit this can also be cost effective as well. You could of course purchase a window unit for your sump or aquarium room. Window units are not the most efficient and really we discouraging you from going that route. Whichever route you choose, your fish and corals will be happy with a steady aquarium temperature.
