Fritz Expel-P is an anthelmintic (deworming) medication and immunostimulant agent. It is safe to use in both freshwater and saltwater aquaria and is effective against many internal parasites, especially nematodes, when used as directed. It does not harm the bio-filter, plants, other invertebrates or uninfected fish. As an added benefit, it boosts the immune competence of fish.

Fritz Expel-P is effective against Nematodes, Roundworms, Nodular Worms, and Hookworms.
Symptoms can include worms visibly protruding from the anus of the fish, wasting, abdominal bloating, disinterest in food, or rapid breathing or gasping, Can also be used as a coral dip to treat for flatworms and pest nudibranchs.

Expel-P does not treat Cestodes (tapeworms) or Trematodes (flukes). For these parasites, try Fritz ParaCleanse

Active ingredient: Levamisole HCl

Directions & Dosage

Standard Treatment: Use 1 packet Expel-P per 10 gallons (38 L) of water. Perform a 25% water change taking care to remove excreted worms/parasites after 24 hours. Repeat the treatment one week later to prevent reinfection. Repeat weekly treatments as necessary. See below for instructions on treating tanks smaller than 10 gallons.

Coral Dip Directions:
Use three packets Expel-P per two gallons (8 L) of salt water. Place affected corals into dip for up to 30 minutes with adequate water flow to assist in worm removal. Once worms stop falling off, the coral can be returned to display or quarantine tank. Treatment does not affect eggs - remove manually or repeat treatments after hatching. Treatment can be repeated once per week, up to three times.
