Buying advice

When choosing an aquarium chiller, consider tank size, desired temperature drop, ambient temperature, and budget. Compressor chillers (1/10 HP and above) are more powerful and reliable for larger tanks, while thermoelectric chillers suit small tanks but struggle with high heat loads. Look for features like titanium heat exchangers, digital controllers, and quiet operation. Ensure proper flow rate matching with your pump to avoid inefficiency.
