Coral Reef Research, Inc. (Natureef) Y2K Zyme

A powerful proteolytic digestive enzyme. This new solution prevents the build up of organic material in the gravel and nooks and crannies of live rocks. Each ounce has Super Catalytic Punch to disintegrate more than a pound of protein like gunk that accumulates in every crevice and corner of your tank. By eliminating the gunk it prevents the formation of noxious sulfur and carbon compounds that suppress natural seawater's oxidative potential. It greatly lowers the chemical oxygen demand (COD) that robs your water of oxygen. Because of its tremendous working capacity, it can be used to clean up old systems, aid in cycling new tanks and is especially beneficial during curing of live rock. K Zyme helps keep your tank sparkling clean. K Zyme is available in 16 oz and 32 oz bottles.
Use the spray bottle to spray directly on biomedia and rotating biological filters.
