Miracle Mud-Freshwater Tray 2lb

Miracle Mud is the original refugium mud substrate developed by Leng Sy in late 1989. Miracle Mud is comprised of up to 80% oceanic mud, harvested from deep ocean water and then dried on land. The remaining 20% is a formulation of minerals and trace elements that make Miracle Mud a true MIRACLE. 

It continuously replenishes the mineral and trace element concentration in the aquarium water, creating the ideal environment for fish and plants. 

Miracle Mud makes an ideal and highly efficient refugium filter, leading to a pristine environment for the fish in the aquarium. The fine consistency of Miracle Mud produces distinct aerobic and anaerobic layers that enable it to be both an excellent nitrifier, as well as a denitrifier. Miracle mud is the most economical refugium filter substrate to use if the goal is to remove nitrate from the system water!
