Gravel & Substrate Cleaner Clean Aquarium Substrates Without Removing Them For SALT & FRESH WATER Provides rapid and natural sludge & muck removal 80% faster than bacterial products alone Reduces and binds nutrients including phosphates Organic and microbial based Natural & Non-Caustic Years in development, MICROBE-LIFT/ Gravel & Substrate Cleaner speeds the biological breakdown of slow to degrade organic waste matter from aquarium bottoms that may become toxic to fish and plant life.

These gaseous by-products endanger fish, marine life, and plants.

MICROBE-LIFT/ Gravel & Substrate Cleaner contains natural cellulosic matter, select biological accelerators and special microbes proven effective in aquarium sludge reduction. MICROBE-LIFT/ Gravel & Substrate Cleaner will also help to clarify dirty aquarium water. Recommended for use with all MICROBE-LIFT bacteria and enzyme products.
