Overview
Seachem Focus is an antibacterial polymer made to treat internal infections in fish while keeping medication where it belongs. It can be used on its own or mixed with other treatments to make them more palatable and limit loss into the water. Because fish find it appetizing, Focus delivers medication internally without contaminating the entire tank.
