Product details
MetroCleanse 20 Count – Fritz is a metronidazole-based aquarium medication used to treat suspected internal and external infections in fish systems. It can be administered either as a broadcast treatment or mixed into medicated food, making it a practical option when you’re managing symptoms and want to target infection rather than just manage water quality. For best results, it is recommended to use MetroCleanse in a quarantine tank so you can monitor response and control treatment conditions. If symptoms do not improve, dosing can be repeated according to the package-style guidance provided with this product listing, then the tank can be returned to normal filtration and feeding once symptoms have resolved.
Features:
- Active ingredient: Metronidazole, used for internal and external infections
- Two administration methods: broadcast dosing or medicated-food dosing
- Broadcast guidance: do not broadcast over invertebrates (remove all invertebrates prior to dosing)
- Medicated-food method is stated as safe for invertebrates, including corals, snails, shrimp, clams, and other crustaceans and molluscs
- No contraindications are stated for use with the shop’s other products and medications
- Tank support guidance: remove activated carbon and ion-exchange resins; discontinue skimmer and UV sterilizer during treatment
- Once symptoms stop, replace chemical filtration; use protein skimmers and resume normal feeding
