Collection: Major Elements

Seachem's supplements for the three elements a reef uses fastest - calcium, alkalinity and magnesium - plus the buffers that hold pH. Reef Builder and Reef Carbonate raise alkalinity, Reef Calcium and Reef Advantage Calcium raise calcium, and Reef Advantage Magnesium tops up magnesium. Reef Buffer and the Marine Buffers set and hold pH, with Marine Buffer intended for fish-only systems. Powders run up to 4 kg tubs for larger systems.

Alkalinity

Reef Builder – powdered alkalinity without a sharp jump in pH, from 300 g to 4 kg.
Reef Carbonate – liquid alkalinity in 500 mL and 2 litre bottles.

Calcium and magnesium

Reef Calcium – liquid calcium, 500 mL and 2 litres.
Reef Advantage Calcium – powdered calcium for reefs with high daily demand.
Reef Advantage Magnesium – powdered magnesium, 600 g and 1.2 kg.

Liquid or powder

The liquids are easy to measure in small daily doses and run well through dosing pumps. The powders are dissolved before use and suit larger reefs, where a single tub lasts through many weeks of dosing.

pH buffers

Reef Buffer raises pH and alkalinity together and comes in a 500 g tub. Marine Buffer holds pH in fish-only tanks and comes in 250 g, 500 g and 4 kg, and Liquid Marine Buffer is a liquid marine pH buffer. Check magnesium first: when it runs low, calcium and alkalinity become hard to hold steady.

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.
