Fritz Expel-F is safe and effective anti-fungal medication for treating infections such as Ichthyophonus hoferi and Saprolegnia, as well as certain other true fungal infections. Fungal infections are generally characterized by white, patchy, cotton-like growths on the body, mouth, or fins. Fungal infections usually occur as secondary infections from a previous wound or injury. Without treatment, fungal infections will spread and ultimately cause death. Fritz Expel-F will negatively affect Bryopsis algae growth.
Use one packet of Expel-F per 10 gallons (38 L) in a small container or glass, mix, 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.
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 signficantly affected by Expel-F.
