Biological Filter Additive for Aquarium - Api Stress Zyme

Support a cleaner, healthier aquarium with API Stress Zyme — a biological filter additive containing live bacteria that enhances filter development and helps maintain optimal water conditions.

Organic waste and pollution can accumulate in aquariums, slowing the growth of beneficial nitrifying bacteria and disrupting the biological filter. API Stress Zyme works by consuming harmful organic pollutants, helping to create the ideal environment for beneficial bacteria to thrive. This accelerates the development of the biological filter in newly established tanks and keeps existing systems running efficiently.

By keeping gravel and filter media cleaner, Stress Zyme also helps reduce conditions that encourage disease-causing organisms — improving overall water quality and living conditions when used regularly.
