Collection: Heating & Chillers

Hold a Stable Temperature

Livestock handles a steady temperature far better than a swinging one. Most tanks need a heater to hold their setpoint through the night and cooler months; tanks that overheat under lights and pumps — or coldwater systems — need a chiller to pull heat back out. A thermometer keeps you honest either way. We carry temperature gear from Eheim, Aquatop, Aqueon, JBJ, and EcoPlus.

What's in This Collection

• Heaters — titanium and glass aquarium heaters from nano wattages up to large systems.
• Chillers — titanium heat-exchange chillers for reef, coldwater, and warm rooms.
• Thermometers — floating, stick-on, and digital thermometers to monitor temperature.
• Cooling fans — clip-on fans that shed a few degrees through evaporation.

Match heater wattage to your tank volume, and size a chiller to your system and room — undersizing either just means it runs constantly without holding target. Larger chillers ship as heavy freight; email info@jlaquatics.com before ordering so we can confirm delivery. J&L has kept Canadian tanks stable since 1997.
