Calcium chloride dihydrate is an odourless white solid in the form of small flakes. It is deliquescent (absorbs moisture from the air) and rapidly dissolves in water producing heat (exothermic). It is commercially produced by the Solvay Process. It has many industrial applications and is commonly used to prevent dusting, as a drying agent and to melt ice. It is used in swimming pools and aquariums as a pH buffer and a rapid source of calcium ions.

Uses for calcium chloride
Directions for use will depend on intended application. Please contact office for specific requirements.
How to use in Aquariums & Reef tanks:
Increasing 1 dGH of Calcium (7.14691 ppm) in 1 litre of water using Calcium Chloride:
7.14691 / (40.078 / 147.01396) = 26.21626 mg/Litre
Therefore to raise the calcium levels by 10ppm in 100L of water you need to add 3.67g of calcium chloride.
Optimum level should be approx 380 - 450ppm (ideally 420ppm). It is not advisable to raise calcium levels by more than 20ppm per day.
Calcium chloride for ice melting
This is an efficient method for the removal of ice and snow from paths, drives and walkways. It works by reacting with moisture to create heat which instantly starts melting the ice. It reacts 8 times faster than conventional salt and operates at temperatures below -25C. As it penetrates the ice it fractures the structure of the ice which ultimately collapses when walked on or driven on.
It leaves no corrosive residue like salt which can damage carpets making it ideal for use around entrances of offices, nursing homes, factories, car parks, restaurants, schools etc. It also helps to stop ice forming on surfaces and can be used for preventative maintenance.
To use, simply sprinkle a handful per square metre of ice and let the product get on with it.
Directions for use will depend on intended application.

TREATMENT OF BITTER PIT & CORK SPOT
To use as foliar spray: Dilute 1kg of calcium chloride for every 420L of water. Apply by spraying over leaves every 2 weeks for 5 weeks up to two weeks before harvesting.
