Two Directions, One Goal

Temperature control means being able to move heat in both directions. A heater adds warmth to hold a setpoint overnight and through winter; a chiller removes heat when lights, pumps, and summer push a tank too high, or when you're keeping a coldwater species. Steady beats warm-or-cool every time.

The Equipment

  • Heaters — titanium and glass units sized from small tanks to large aquariums.
  • Chillers — refrigeration-based coolers with titanium heat exchangers for saltwater safety.
  • Thermometers — floating, adhesive, and digital readouts to track your temperature.
  • Cooling fans — surface fans that drop a few degrees through evaporative cooling.

Size heater wattage to tank volume and chiller capacity to both tank and room — an undersized unit runs nonstop and still misses target. Full-size chillers are heavy and ship as oversized freight, so plan delivery accordingly. Questions on sizing? Email info@jlaquatics.com.

J&L Aquatics was formed in December 1997

Our business was started from our love of the aquarium hobby. We at J&L Aquatics felt that the Canadian aquarist should have the option to purchase top quality supplies, equipment and livestock other than the generally over priced local retail stores.
