Proven Efficacy

Testing proves that STRESS COAT reduces stress in fish
Stress is the leading cause of poor health and disease in aquarium and pond fish. Fish are stressed by netting, bagging, fighting and poor water quality. A fish's slime coat protects against disease and helps heal small wounds but is often disturbed by netting, fighting and accidental scrapes. Stressed fish are highly susceptible to disease problems because their immune system is suppressed. When fish are stressed their body produces a stress hormone called cortisol. Cortisol is a measurable indicator of fish stress. Corticol is released into the aquarium waters through gills and urine.

In this test goldfish were netted and moved to a series of individual aquariums. Next half of the fish were treated with STRESS COAT and half were untreated. The stress hormone cortisol was measured over time in treated and untreated aquariums. THe results showed a statistically significant 40% reduction in cortisol in the STRESS COAT-treated fish compared to the untreated fish.

STRESS COAT promotes healing of damaged tissue
In another test fish with similar wounds were separated into two groups. One group was treated with STRESS COAT. The second group was left untreated. Veterinarians later examined the wounded tissue and determined that the STRESS COAT treated fish had healed significantly faster than the untreated fish.

STRESS COAT with Aloe contains natural healing proteins and minerals, similar to a fish's natural slime coat. STRESS COAT replaces a fish's damaged slime coat with a protective healing layer or natural aloe extract. STRESS COAT acts as a bandage, speeding the healing of damaged tissue.

API Stress Zyme, 64-Ounce

Stress Zyme is a biological filter additive containing live bacteria that improves the development of the biological filter and helps clean a dirty aquarium. The build-up of organic pollution in the aquarium inhibits the growth of nitrifying bacteria. The bacteria in Stress Zyme keep conditions in the aquarium right for the development of the biological filter by consuming harmful organic pollutants. This speeds the development of the biological filter in newly set up aquariums. A build-up of organic compounds also promotes the growth of disease-causing organisms in the aquarium. Stress Zyme keeps the biological filter working properly by keeping the aquarium gravel and filter clean. Water quality and living conditions are improved when Stress Zyme is used on a regular basis. Each teaspoonful of Stress Zyme contains 300 million bacteria. These bacteria are in a dormant state and become active when added to the aquarium. Stress Zyme has a five-year shelf life and does not require refrigeration. Stress Zyme is effective in freshwater and marine aquariums.
