Microbe-Lift Gravel & Substrate Cleaner is specially designed to clean up organic wastes such as fecal matter, muck and sludge while clarifying your aquarium water with cellulosic matter, select biological accelerators and unique microbes. This cleaner prevents harmful gaseous compounds and by-products found at the bottom of the tank from spreading around the atmosphere.
Water will discolor as formula is black in color, for approximately 48-96 hours after use.
