Fish Flex Antibiotic

Fish Flex (Cephalexin 250mg) is for use in aquariums for the treatment of bacterial activity.  Cephalexin is a cephalosporin antibiotic and acts by inhibiting the synthesis of bacterial cell wall, leading to cell death.  Cephalexin is active against both gram-positive and gram-negative bacteria.  Resistance can develop among some gram-negative rods (e.g., E. coli).

Directions:

Add one capsule (250mg) into aquarium for each 10 gallons of water.  Repeat in 24 hours.  It is suggested that a partial water change be made between treatments.  While treatment duration depends on the type and severity of infection, it is recommended that extended baths in the medication continue for a minimum of 5 days and for not more than 10 days.  Discontinued treatment if no improvement is noted within 5 days.
