ALKEN CLEAR-FLO® 1200 is a specially designed synergistic combination of bacteria for degrading organics rapidly and two species of nitrifying bacteria to remove ammonia, which can be harmful to fish at low levels. ALKEN CLEAR-FLO® 1200 is ideal for use in fish hatcheries, fish and prawn farms, lobster pens, and aquaria to combat the most common problems associated with high nutrient levels -- murky water, fish suffocation and off-flavors. ALKEN CLEAR-FLO® 1200 also degrades nominal contamination levels by pesticides and other synthetic organic contaminants. It is ideal for seeding biological filters.

• Promotes a healthy aquatic environment.
• Reduces or eliminates losses of stock due to organic pollution or toxic ammonia concentration.
• Eliminates turbidity and murky water.
• Reduces sludge buildup and hence the potential for anaerobic conditions.
• Reduces or eliminates off-flavor problems.
• Effective over a wide temperature range (49F to 105F) and a wide pH range (6.5 to 9.0).

 See Aquaculture/Lake/Pond dosage charts for average application rate. for general application rates. General initial dose is 1 to 2 gallons per hectare. Be aware that a heavy rainfall may bring significant contamination with its runoff, and a one-time dosage equal to the initial application may be needed to restore control. Mechanical aeration may be needed where natural aeration is deficient. Nitrifiers consume 7.2 ppm of alkalinity for each ppm of ammonia oxidized to nitrate, so adjust alkalinity if necessary to stay within that range. Do not use algaecides, herbicides or antibiotics in the pond, when using ALKEN CLEAR-FLO® 1200, because they may kill the bacteria.

Shrimp farmers have generally switched to using the newer combination of CF 1006 and CF 1100-50x for better product shelf-life and reduced shipping costs. These two products are also available with a shorter lead time than the three weeks preparation required for CF 1200.

ALKEN CLEAR-FLO® 1200 is packaged in 5 and 55-gallon containers. Store in a cool place. Avoid contact with eyes, skin, and open wounds. Wash hands with warm, soapy water after handling.
