Zeolite is a naturally occurring volcanic rock that is mined in Australia and is Certified Organic and can be used in various applications.  It is a preferred Water Corporation soil amendment. It works equally well in soil as it does in water. It can be mixed directly into the soil to maximise nutrient retention, act as a growing bed for vegetable seedlings in aquaponics and zeolite is great for controlling algae.

Zeolite is hydrophilic, Its structure allows it to absorb and store a great percentage of its mass in water, that can still be accessed by plants and soil organisms. But at the same time, it also entraps air - so necessary for healthy active root growth and beneficial organisms.

It is also available in  0.5mm Sand 10kg bag


Spongolite (and Zeolite) are a natural, certified organic and endorsed product by the Water Corporation of Western Australia as a preferred soil amendment. Being an organic product you can be assured that you can never overdose these products, infact, using more will always be better.
