Seachem StressGuard is a premium slime coat protector for marine and freshwater aquariums. Using a unique formula, StressGuard reduces fish stress from transportation or handling, promotes healing, and acts as an antiseptic to reduce the risk of infection. Premium slime coat protection product for fresh and saltwater aquariumsReduces stress when handling or transporting fishPromotes healing and acts as an antiseptic for fishStressGuard is compatible with all non-copper based medications. It is not amine-based and will not interfere with Purigen or HyperSorb, and does not coat resins or clog filtration like other slime coat products can. What sets StressGuard apart The secret is a protein active colloidal agent that actively seeks out any wounds, abrasions, or exposed proteins, and attaches to the area to deliver disinfectant and begin healing. In the process, the agent also acts as a liquid bandage to keep the abrasion protected. And unlike other slime coats, StressGuard has a pH of 7. 0 - meaning it will never interfere with the pH of your aquarium, even when used in large doses. Directions: Use 1/2–1 capful (2. 5–5 mL) to every 10 gallons (40 L) daily until signs of stress have abated or healing is complete. Dose may be safely doubled.
