Natural Zeolite-Aquaculture
Advance Granular Zeolite

Product Information

Ammonia ‘sinks’ occur within pond aquaculture in the form of the plants and algae. Large quantities of organic matter are produced by algae or added to pond as feed. The decomposition of this organic matter like unutilized feed, dead plants & fish, excretion of fish, remains of FYM etc produces ammonia which diffuses from the sediment into the water column. It also releases other gases like Sulphur dioxide and Hydrogen sulphide. High ammonia is also caused by inadequate or immature biological filtration, over stocking of fish, over feeding of fish & high temperature.

Zeolite is a naturally occurring deposit (i.e. rock) that has unique structure. Zeolite earth in crude form gives many types of crystals. Only micro crystalline alkali earth metal, aluminum Silicates are known as zeolite. This is because the absorption of gases takes place through the surface area, which is highly porous whilst also allowing for rapid uptake and loosing of charged particles. Zeolite filters ammonia and holds it inside its porous structure. Therefore, only micro crystalline form of zeolite having tetrahedral structure with maximum calcium form are useful in aquaculture. This is because calcium ion is easily exchangeable with ammonium ion.

Aquamac GLAMZEX/GLAMZEX-XT absorbs ammonia & other toxic gases through its high ‘Cationic Exchange Capacity’ thus developing a healthy environment in pond for prawns and fishes to grow.


  • Absorbs Ammonia, H2S and other toxic gases from pond
  • Purifies the water quality of pond and absorbs the stink rapidly – develops healthy environment
    for prawns and fish growth
  • High Cation Exchange Capacity (CEC) Value – effective in high range of pH and salinity

Usage & Recommendation

For pond preparation: 25-30 Kg or more per acre
During Culture: 15 Kg/acre in every 15 days (1 meter depth)

For pond preparation: 20 Kg or more per acre
During Culture: 10 kg/ acre in every 15 days (1 meter depth)

Or as per recommendation of Aqua Consultant


Should be broadcasted uniformly throughout the pond.

The requirement varies depending upon the pH, water temperature, water quality & volume and species stocking density.

Storage & Handling

GLAMZEX: 25 kg Bag
GLAMZEX-XT: 10 kg Bucket

Reduce ammonia, creates healthy environment for fish & prawn
