StressGuard is the premier slime coat protection product. StressGuard reduces stress and ammonia toxicity resulting from handling or transporting fish. StressGuard binds to exposed protein in wounds to promote healing of injured fish and to reduce the likelihood of primary and secondary infections. StressGuard is compatible with all medications except those that are copper based. StressGuard is not amine based and will not interfere with Purigen regeneration. StressGuard does not coat resins or clog filtration like competing “slime coat” type products can.



  • Reduces stress from handling or transport
  • Antiseptic for fish
  • Promotes healing
  • Reef Safe


What makes StressGuard very successful at healing is the fact that it contains protein active colloids. This protein active colloidal agent actively seeks out and binds to any wounds, abrasions, or places where exposed proteins are and attaches to this area to help directly deliver the disinfectant, preventing infection and allowing the healing process to start. This protein active colloid, because it binds to the exposed proteins, also acts like a liquid bandage to the abrasion. Some products are marketed to be squirted in the bag when a fish is purchased. Those products are generally acidic, with some brands being a very strong acid. Putting such a product in a small, enclosed container with a fish often does more harm than any intended good. StressGuard has a pH of 7.0. It will not affect the pH of an aquarium, even at large doses. There are no other products on the market that can compare to the effectiveness of StressGuard.



  • Use ½ to 1 capful (2.5 to 5 mL) for every 10 US gallons (40L) daily until signs of stress have abated or healing is complete.

Note: Dose may be safely doubled.
