GroTech Zeolith, 1000ml
eoliths are water-containing, felspar-like silicate minerals.
The inside and outside surfaces can amount to up to 600 qm/ccm.This enormous surfaces offer for example for nitrogen decomposing microorganism an ideal habitat. The mentioned characteristics convert Zeoliths into natural ion exchangers,for example adsorption ability for Ammonium.
Besides the characteristic as ion exchanger, Zeoliths are, due to their porousfine structure,like nearly no other substrate, mechanical filters.Heavy metals and toxic metabolic products are absorbed and chemical -bio-logical rebuilt.
Grain size: 4 - 8mm
