Seachem Focus™ – Antibacterial Polymer for Targeted Medicated Feeding
Seachem Focus™ is a specialized antibacterial polymer designed to treat internal infections in fish by binding medications directly to their food. Its active ingredient, polymer-bound nitrofurantoin (0.1%), effectively treats internal bacterial and fungal infections while preventing the medication from diffusing into the water column. By delivering treatment straight to the fish's digestive system, Focus™ is the ideal solution for treating sick fish in reef or planted aquariums where sensitive invertebrates and plants would otherwise be harmed by broadcast water treatments.
Precision Treatment & Invertebrate Safety
Focus™ is the cornerstone of the "Medicated Food Mix," providing a safe and efficient way to medicate your aquarium without affecting your biological filter or water chemistry.
-
Binds Medication to Food: Dramatically reduces the loss of expensive medications to the water through diffusion, ensuring the fish ingests the full therapeutic dose.
-
Reef & Planted Tank Safe: Because the medication is bound to the food and eaten, it does not contact delicate corals, shrimp, or snails, making it safe for diverse community tanks.
-
Ideal for Internal Infections: Specifically targets pathogens causing bloating, abnormal stools (white/stringy), and loss of appetite—symptoms often seen with Dropsy or Hexamita.
-
Allows Dual Treatment: Enables a "two-pronged" approach where one medication can be added to the food for internal issues while another is added to the water for external parasites.
-
Reduces Environmental Stress: Eliminates the need to catch and move sick fish to a hospital tank, which can further weaken an already stressed animal.
FAQ Section: Common Questions
-
Can Focus™ be used as a medication on its own? While Focus™ contains nitrofurantoin, it is primarily intended as a binding agent. For specific diseases, it should be combined with a targeted medication like MetroPlex™ or KanaPlex™ for maximum efficacy.
-
How do I make a medicated food mix? Mix 1 scoop of Focus™ with 1 scoop of the medication of choice (e.g., MetroPlex) and 1 tablespoon of food (frozen or pellet). Add a few drops of water or GarlicGuard™ to moisten, stir, and feed.
-
How long can I store the medicated food mix? The prepared medicated food mix can be refrigerated for up to 24 hours or frozen for longer-term use, allowing you to prep multiple feedings at once.
-
How often should I feed the medicated mix? Feed the medicated food once daily (as much as they can eat in 1 minute) for at least one week, or until symptoms disappear and the fish returns to normal behavior.
