Collection: Major Elements

Brightwell's major element range for reef aquariums: two-part liquid calcium and alkalinity, a dry alkalinity powder in both jar and pail sizes, magnesium, kalkwasser, a pH buffer and a coralline accelerator. Containers run from 450g and 500ml up to 2 litres and a 4KG pail, so a nano and a heavily stocked system can both buy sensibly. Follow the dosing instructions on each label and test before you increase a dose.

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.
