Overview

Expel-F is a quick and effective treatment for infections of true fungal infections on fish and eggs (whitish tufts of cotton-like material).

Fungal infections are usually found at the site of an injury or recent attack from parasites. A true fungal infection has a cotton-like appearance similar to a mold found on fruit, bread or cheese, except that on fish, it is usually white instead of black or green. Fungal infections can be difficult to treat and are usually secondary invaders resulting from an injury on the fish or recent wounds from parasites or bacterial infection.

Active Ingredient: Fluconazole

Indications

Expel-F successfully controls true fungal infections caused by Saprolegnia, Ichthyosporidium, egg fungus and related species, and some other external symptoms, such as fin and tail rot.

Saprolegnia

Fin & Tail Rot

Ichthyosporidium

Secondary Infections

Fish Egg Fungus

Consult a veterinarian or fish expert for assistance in diagnosis of disease-causing organisms and treatment options.
All suspected bacterial infections should be treated immediately.

Common symptoms

Symptoms of possible fungal infection can include clamped fins, swollen eyes, heavy or rapid breathing, patchy coloration, change in swimming behavior or corner-hiding.

Fungus

White tufts of cotton-like material found on fins, tail and/or body at sites of injury.

Fin and Tail Rot

Split, ragged or deteriorating fin and/or tail.

Preparations & Directions

Preparations
  • Use of a hospital tank is recommended.

  • Remove all chemical filtration (carbon, ion exchange resins, etc) and stop use of skimmer (if present) during treatment.

  • Maintain aeration and water flow.

  • Do not perform water changes during the treatment period if possible. If ammonia is a concern, neutralize it with a water conditioner like Rescue A.C.C.R. or Complete
Directions
  • Use one packet Expel-F per 10 gallons (38 L) in a small container or glass, mix with a small amount of water from aquarium, and add to a high flow area in sump.

  • Powder will dissolve in system over time. Treatment only requires one dose of medication. Treatment period is 14 days.​

  • If necessary, you may perform a second course of treatment. If no further symptoms are observed, replace chemical filtration and resume use of protein skimmers as well as normal feeding. Adjust temperature back to normal.​

Notes

Compatibility

  • Expel-F is compatible with many fresh and saltwater species, equipment and most Fritz products.

  • May be safely used along with other treatments: Coppersafe, Maracyn, and Maracyn Two.

  • PLEASE NOTE: Expel-F will affect desirable macroalgaes and may cause some corals to retract temporarily. Use with caution in systems containing these species. It will not affect hair or turf algaes. Bryopsis algae is significantly affected by Expel-F.

Small system dosing

Dividing up our powder packets accurately for use in smaller tanks can be tricky, and to get the proper dose we recommend making a concentrated solution that is much easier to measure, see video below

Example small-system dosage

  • For a 5 gallon aquarium: mix/dissolve one packet mixed in 1/2 cup of water from the aquarium. One 5 gallon dose is equal to 1/4 cup of solution.

  • For a 1 gallon aquarium: mix/dissolve one packet in 10 tbsp of water from the aquarium. A 1 gallon dose is equal to 1 tbsp of solution.

  • For tanks in between the previous options, add the amount of 1 gallon doses equal the gallon size of your tank.

  • Store any excess solution in the fridge between doses, for up to a week.

Treatment may inhibit nitrifying bacteria. Monitor ammonia and nitrite levels during treatment.
