Shrimps, snails and other aquatic invertebrates require calcium in their environment. We recommend you maintain your aquarium’s calcium levels as it is an essential mineral for optimum health, growth and shedding with shelled invertebrates. If calcium levels are low or depleted, this will reduce or inhibit the ability of many organisms to grow or repair themselves if they are damaged.

Directions: Always add this product into flowing water to disperse calcium throughout the aquarium. Adding 1ml to 20 litres or 5ml to 100 litres of water will raise calcium levels by approximately 10ppm.
