Seachem StressGuard is a premium slime coat protection product for freshwater and marine aquariums. It reduces stress and ammonia toxicity during fish handling and transportation. Its active protein colloids bind to exposed proteins in wounds and abrasions, helping promote healing and reduce the likelihood of primary and secondary infections. StressGuard is compatible with most medications, except copper-based treatments, and does not significantly affect aquarium pH. Available in a 250 mL bottle.
