Seachem Focus 5g (641) is an antibacterial polymer treatment designed for internal infections in fish. It is intended to be mixed with food and/or other medications to help make the medication more palatable and reduce how much medicine diffuses into the water. Focus can be used in both freshwater and marine aquaria, making it a practical option when symptoms suggest an internal problem rather than an external one.

- Antibacterial polymer for internal infections in fish
- Best used as a medicated-food mix to improve palatability
- Helps reduce medication loss to the water through diffusion
- May be used alone or combined with other medications as directed by your overall treatment plan
