Collection: Hanna Checkers

Hanna Checkers replaced colour-card guesswork for a lot of reefers: a colorimeter reads the sample and gives you a number, so two people testing the same tank get the same answer.

The range here covers Checkers for alkalinity (dKH), calcium, magnesium, nitrate, phosphate (low range), phosphorus (low range) and copper (high range), plus marine pH and salinity testers and handheld pH/conductivity/TDS meters. Matching reagent packs and calibration solutions are stocked separately — each Checker uses its own. Not sure which you need? Email sales@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.
