Get quick answers to common questions about Chillers & Fans

What size aquarium chiller do I need?

The size of your chiller depends on your aquarium’s total water volume, heat sources, and the temperature difference needed. Generally, the larger your tank or the warmer your ambient room, the higher the BTU/hr or cooling power required. Product listings on Charterhouse Aquatics specify suitable tank sizes for each model.

Are fans or chillers better for cooling an aquarium?

Fans are great for small to medium tanks with slight overheating issues and are more energy-efficient. Chillers, on the other hand, are ideal for larger systems, reef tanks, and cases where consistent temperature control is essential. In extreme cases, a fan alone may not be sufficient.

Can I use a chiller with a reef tank?

Absolutely. In fact, chillers are often essential in reef systems where temperature stability is critical for coral health. Many reef aquarists rely on chillers to offset heat from strong lighting or enclosed cabinetry.

How do aquarium fans cool the water?

Aquarium fans promote evaporation at the water surface, which naturally lowers the temperature. While not as powerful as chillers, fans are easy to install, energy-saving, and effective in moderately warm conditions.

Do I need a controller or thermostat?

Most aquarium chillers include built-in digital thermostats, but for fans or non-integrated setups, a dedicated aquarium temperature controller can help automate and safeguard your tank’s climate.

Stay Cool, Keep Your Tank Stable

Temperature fluctuations can cause stress, illness, and even death in sensitive aquatic species. That’s why choosing the right cooling solution—whether a compact aquarium fan or a full-performance chiller—is one of the smartest investments you can make for your tank’s long-term health.
