MicroChoice ® ACT

A feed additive and water treatment product formulated to promote the production of healthy shrimp and fish.

MicroChoice® ACT’s biologically active formula contains a proprietary blend of bacterial strains that were selected for the ability to breakdown excess waste material in shrimp ponds while helping to protect against shrimp and fish pathogens.

Non-engineered cultures were selected for optimum enzyme production, assuring efficient breakdown of proteins, carbohydrates, cellulose and fats. This leads to better feed conversion and less waste material in your pond which results in cleaner water and higher oxygen levels.

Scientifically selected cultures colonize the animal gut aiding in feed digestion and help to prevent infection by pathogens.

Bacteria are stabilized and shipped in spore form, ensuring long term stability and extended shelf life.

Multilevel quality assurance processes extend far beyond our doors. Purity and microbial concentration is guaranteed for consistent and superior biological products in the hands of your customers. Formulation assistance and recommended dose rates are available.
