Fritz-Zyme Laboratory Testing
Performed by the University of California

Below, images from an electron microscope show test results.
Testing was performed over a 14 day period with readings taken every two days. A known amount of ammonia was added to flasks. Nitrite and nitrate presence resulted from ammonia conversion.

An electron microscope shows Fritz-Zyme #7 as the only product to form large, uniformly developed bacterial mats on biofilter medium.

Products showing slight ammonia removal created small, broken bacterial mats covering biofilter medium.

An uncolonized calcium carbonate chip was typical of products that removed no ammonia or nitrite.
