StressGuard is the premium slime coat protection product. StressGuard will reduce stress and ammonia toxicity whenever 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; or HyperSorb regeneration. StressGuard does not coat resins or clog filtration like competing “slime coat” type products can.

What makes StressGuard very successful at healing is the fact that it contains protein active colloids. This protein active colloidal agent actively seeks out any wounds, abrasions, or places where exposed proteins are and attaches to this area to help directly deliver the disinfectant in the product and start the healing process. 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.

Pack Size

100 mL bottle.

Seachem make this line in sizes from 50 mL to 4 L

StressGuard is dosed at 2.5–5 mL per 40 L daily, so a 100 mL bottle covers roughly a fortnight of daily dosing on a 100 L tank — enough for one course of treatment.

Buy the size you will get through in a reasonable time and keep the bottle closed, cool and out of direct sun. A part-used bottle that has stood open for a year is poorer value than a small fresh one whatever it cost per millilitre.

Freshness & Storage

Every batch we dispatch carries a minimum of 6 months' remaining shelf life. Store this product in a cool, dry place away from direct sunlight, with the cap or inner foil closed tightly after each use.
