Focus

Focus (by Seachem) is not a standalone medication — it’s a medication binder for fish food used in aquarium treatments. It helps you attach antibiotics or parasite meds to food so fish actually ingest them instead of the medicine dissolving into the water. What it does: Binds medication to food (makes medicated food) Helps fish absorb treatment by eating it directly Reduces medication loss into the tank water Works in both freshwater and saltwater tanks Active ingredient: Polymer-bound nitrofurantoin (very low concentration)   How it’s used: You mix it with another medication + food, usually: MetroPlex (parasites/internal issues) KanaPlex (bacterial infections) NeoPlex / other Seachem meds
