Alken-Murray Corporations distributor, Ing. Luis Javier Rodgriguez Ortiz prescribed a treatment regimen of Alken Clear-Flo® 1200 for the Zoologico Guadalajara in Mexico. An initial sample of water was withdrawn for testing on August 14th and compared with a water sample withdrawn September 4th, 1998. 
 After 21 days of treatment with CF 1200 in their alligator and animal ponds and aquariums, BOD and COD levels decreased by 84%, the level of total suspended solids decreased by 93%, TKN decreased by over 50%, oxygen levels increased from 0.1 ppm to 2.0 ppm, water clarity improved by 26%, pH increased from 6.8 to 7.5, and sediment decreased from 2.0 to 0!
