 Maintenance Feedrate

 Kitchen drain  1 Tbs per inch diameter of drain  Weekly
 Laundry drain  1 Tbs per inch diameter of drain  Weekly
 Bathroom drain  2 Tablespoons  Weekly
 Toilets  2 Tablespoons  Weekly
 Grease trap  1 cup in drain close to trap  Once a month*

*For initial dose & problem systems: double the suggested feedrate for the first two weeks or until control is achieved, then continue with dosage as suggested above.


To optimize the action of the bacteria, we recommend pre-hydrating for 1 to 2 hours after adding 2 gallons of water at 70 F to 90 F to each pound of product. Make sure water is free of chlorine. Pour entire product, including bran into system. Alternatively, dry powder may be applied directly to the system, either loose or in soluble packets. Avoid use of algaecides, herbicides, and antibiotics when using ALKEN CLEAR-FLO®.
