Reduces stress when handling/transporting fish, antiseptic & promotes healing in marine/freshwater settings. Seachem's StressGuard™ is the #1 slime coat protection product. It reduces stress/ammonia toxicity & binds to injuries, speeding up the healing process. Unlike others, won't coat resins or clog filters. StressGuard™'s protein active colloids actively target wounds to provide disinfectant & act as a liquid bandage. Unlike many others, it has a pH of 7.0 & won't alter aquarium pH, even in large doses. Unmatched effectiveness!
