Aquaculture grade Zeolite with highest Cation Exchange Capacity (CEC).

Zeolite functions in Aquaculture Molecular sieves zeolites are crystaline sodium or calcium aluminium silicates. They are graded or classified on the basis of their average pore diameter.

This material has three dimensional framework structure in which silicone and aluminium atoms are tetrahydrally co-ordinated to oxygen atoms. The framework enfolds cavities containing water molecules and cations that are capable of undergoing dispersion and cation exchange.

A number of organic substance are lying at the pond bottom. These may contain unutilized food, dead plants & fish, excretion of fish, remains of FYM etc. All these substances decay. The proteinous portion in these substances is released in the form of ‘Ammonia’. It also releases other gases like sulphur dioxide, hydrogen sulphide etc.

Before decomposing to ammonia all organic products come to ammonium carbonate form. If Zeolites are present at this stage, they absorb ammonia through its ‘Cation Exchange Capacity’, thus developing a healthy environment for the prawns and fishes to grow.

Zeolite earth in crude form many types of crystals. Only micro crystalline alkali earth metal, Aluminium Silicates are known as Zeolite. This is because the absorption of gases takes place through the surface area. Therefore only micro crystalline form of zeolite shall give desired results. Furthermore, zeolites having tetrahydra structure with maximum Calcium form are useful in Aquaculture. This is because Calcium ion is easily exchangeable with Ammonium ion.
