Share This On


Have you checked your tank’s temperature lately? If you’ve installed a new lighting system in your room or in your aquarium, or if there’s a sudden heat-spell in your area (usually happens during summer months), chances are the temperature of the water for your fish is no longer suitable to keep your precious pets alive and kickin’.

Time to install an aquarium chiller! Duh… Haven’t heard of this great contraption?

Skip the basics, jump to Best Aquarium Chillers

Basically, an aquarium chiller is there to beat the heat, just as an aquarium heater is there to beat the frost (read our blog on aquarium heaters here – 6 Best Aquarium Heaters For Your Fish Tank). And contrary to popular belief, an aquarium does not only need a heater to balance water temperature, it needs a chiller as well.

Aquarium chillers come with thermostat control – it cools the water when the ambient temperature becomes too warm for many types of fish, including ocean fish and other sub-tropical species.

What’s interesting is that there will be times when you’d actually need both the chiller and the heater in succession due to extreme weather changes. Several manufacturers of aquarium chillers did have this in mind, so they made chillers that are modular and can be easily replaced with a heater. Some also come with dual-function switches that allows you to switch from heater to chiller or vice-versa (note, though, that the heater and chiller units are sold separately).

Chillers complement the other components of your aquarium system as it strikes a balance in the temperature that’s crucial to keep a healthy environment in the tank.

Most chillers come in two types:-

  • inline
  • or drop-in.

What you choose to install will mainly depend on how it will go with your aquarium system. If you think your aquarium is too crowded, choose a drop-in. But if you think an inline chiller would go together well with the sterilizer and filter, then go ahead.

There are wide choices of great aquarium chillers out in the market. While features and prices vary, there are those that we think are a notch higher in performance and durability. So, without further ado, may I present the 5 Best Aquarium Chillers:
