From a Test Kit to a Full Controller

Keeping stable water starts with knowing your numbers. Where you land on that spectrum depends on how demanding your livestock is and how much you want automated. We carry testing and control gear from Hanna, Salifert, API, Neptune, Pinpoint, Milwaukee, and Red Sea.

Match the Tool to the Tank

  • Reagent test kits — Salifert and API titration kits for periodic manual checks.
  • Digital checkers — Hanna colorimeters for repeatable calcium, alkalinity, phosphate, and nitrate readings.
  • Meters & probes — pH, salinity, and temperature monitors with calibration solutions.
  • Controllers — Neptune Apex systems that log parameters and switch equipment automatically.

A freshwater community tank runs fine on a master kit and a thermometer. A mixed reef under heavy dosing benefits from checkers and a controller that can catch a heater or return-pump failure before it costs livestock. Not sure where you sit? Email info@jlaquatics.com. J&L has outfitted Canadian aquarists since 1997.

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.
