Overview

• The calcium-bearing component of a two-part method for dosing calcium and carbonates
  (the substances largely responsible for increasing alkalinity ("buffering capacity")) in the
  same ratio as that found in natural seawater.
• Benefits reef-building organisms such as corals, clams, calcareous algae, etc.
• Simplifies calcium and alkalinity maintenance; economical for particularly large systems.
• Contains no phosphate, silicate, or organic material.
• Formulated by a marine scientist.

Technical Background

It is recommended that calcium and magnesium concentrations in the aquarium system be determined by using accurate test kits prior to supplementing. Do not add this product directly to an aquarium containing live animals without first diluting in water as directed. Technical Background: This method of calcium and carbonate supplementation is advantageous to hobbyists interested in a simple and effective means of providing elements and molecules required for skeletal growth of reef-building organisms such as corals, clams, and their allies. The magnesium concentration in all reef aquaria should be adjusted to, and maintained between, 1,290 - 1,320 ppm before using these supplements (alone or together) or other calcium and alkalinity products. Doing so helps prevent unwanted precipitation between calcium and carbonate ions.
