Why Automate Your Water Chemistry

A controller does what a test kit can't: watch continuously. Temperature, pH, ORP and salinity get logged around the clock, and outlets switch on rules you set — so a failed heater or a stuck float valve triggers an alert instead of a disaster. Systems here range from a single-parameter monitor to a full controller running dosing, lighting, return pumps and automatic testing.

Choose by How Far You Want to Go

Single-parameter monitors — a dedicated pH or ORP readout, no computer or app needed.
Full controllers — modular systems with expandable outlet bars, flow and leak sensors, and app control.
Automatic testers — unattended calcium, alkalinity, magnesium, nitrate and phosphate testing, with reagents stocked separately.
All-in-one monitors — combined water quality and lighting measurement from a single unit.

Reagents, calibration solutions and replacement probes are consumables: order them alongside the hardware so a checker or tester doesn't sit idle waiting on a refill. Not sure which system suits your tank? 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.
