Water treatment

Gypsum is used to regenerate and revive aquatic environments such as rivers, ponds, lakes and canals, or to condition and remineralise water in fish farms.

Gypsum can be used as a water treatment additive in many different areas and in different ways. It helps considerably to reduce the level of silt and mud build up by flocculating the clay present.

It assists in clarifying the water and has the ability to neutralise the pH of acidic waters and so improve the development of aquatic life.

As calcium sulphate helps to maintain the equilibrium of calcium in the water, it provides an important means of support to fish.

Benefits

Best Practice

For ponds, lakes and rivers

For ponds and lakes, the product can either be spread mechanically or for smaller areas, it can be distributed by hand. For rivers, the sacks are immersed, cut open and left on the bottom of the river, above the affected site so that the gypsum can be carried away by the current and allowed to dissolve progressively. Gypsum can be applied all year round in temperate environments and in oceans. In colder regions, it should only be applied between March and November. After the first treatment, an annual dose is recommended as an economical method of maintaining the water quality
