Fenbendazole Powder is a highly effective worming agent for freshwater and saltwater tropical species. Using pure veterinary grade powder will offer the most success. Don’t be fooled by some who claim their products are without filler, yet when you weight the packets it is clear fillers are used.
Due to issues with successful treatment of levamisole caused by a resistance build up, Fenbendazole is becoming the better choice.
Can be dosed via water column or mixed with foods.
Treatment: Dosed via water column at 1 teaspoon per 20 gallons (100 mg per gallon). Repeat in 48 hours. And again in 3 weeks if treating camallanus worms or other resistant parasites.
NOTE: When treating via water column Fenbendazole is known to not be readily absorbed, so treatment may not be as effective as dosing in food.
NOTE: Occasionally discus are known to start head standing when having a bad reaction to treating the water column. If fish display any behavioral changes do an immediate water change.
In food, mix 1/8 teaspoon per pound of food. Offer as the only food source for 3-5 days. And repeat in 3 weeks when treating resistant parasites.
10 gram will treat approximately 100 gallons or 25 pounds of food
