The miracle mud release 70 + mineral essential elements to stabilize your aquarium water chemistry;
This stabilization of water chemistry encourage the breeding of fancy ornamental freshwater shrimps (hence we suggest that you introduce a dozen or so in the filter tank). Hence the 'living filter.'
With the thickness of Miracle mud 1" - 1.5" it become a denitrater filter, ie. fixing nitrate into nitrogen and oxygen gases;
Miracle Mud provide best nutrient for plant to grow well. With regular trimming this also help controlling nitrate and phosphate as plant use it to build its biomass.
