Reef Calcium – 100 ml Seachem – Organic Calcium for Reefs

Reef Calcium is a polygluconate organic calcium supplement designed to maintain calcium in reef aquariums without altering the pH.

Its formulation is based on highly bioavailable complexed calcium, allowing corals to absorb calcium with reduced energy expenditure, thus promoting faster and more efficient growth.

SEACHEM

Operating Principle

Unlike ionic supplements, Reef Calcium uses organic calcium linked to a polygluconate. This structure allows calcium to penetrate coral tissues more easily while providing a metabolizable carbon source.

The product contains neither nitrogen nor phosphorus, making it safe for properly maintained reef systems without promoting algae proliferation.

Main Features

Available Sizes

100 ml, 250 ml, 500 ml, 4 L.

Usage Instructions

Add 5 ml per 80 L of water twice a week.

The dose can be increased according to coral growth response, without exceeding 15 ml per 80 L per day.

Each 5 ml dose increases calcium by approximately 3 mg/L.

Recommended Use
