BeneKoi- The Natural Way to achieving Healthy Fish and Clear Water. BeneKoi 16 Oz dry powder formula treats up to 6,000 gallons of pond water at full strength and up to 18,000 gallons at maintenance strength. BeneKoi contains five beneficial microbial strains that work up to three times faster, than the leading bacteria brand, to eliminate sludge and toxic organic waste. It is a natural flocculent that helps to remove organic wastes and decomposes dead algae and leftover food. BeneKoi works to establish superior beneficial bacterial flora in the pond and helps fight diseases caused by harmful (Gram-negative) bacteria (Aeromonas and Pseudomonas). BeneKoi, when ingested by pond fish, serves as a probiotic that boosts fish immune system and aids in the digestion of food. Unlike other brands, there are ten times more effective probiotics that restore a healthy aquatic environment and fight diseases caused by bad bacteria. BeneKoi builds bio-filtration quickly and prevents unhealthy pond conditions by reducing ammonia and nitrite.
