API Stress Zyme 16 oz

The Invisible Cleaning Crew

Maintenance is about more than just water changes—it’s about managing the organic "sludge" that builds up in your gravel and filters. API Stress Zyme is a concentrated biological filter booster that contains over 300 million live bacteria per teaspoon. These specialized bacteria act as a "liquid janitor," breaking down uneaten food, fish waste, and decaying plant matter before they can pollute your water.

Why Stress Zyme is Essential for a Healthy Tank:

• Reduces Aquarium Maintenance: By naturally "eating" the sludge in the substrate and filter media, Stress Zyme significantly reduces the need for frequent gravel vacuuming and filter scrubbing.

• Improves Water Quality: Decomposing organic matter consumes oxygen and can cause ammonia spikes. Stress Zyme keeps the environment clean, ensuring higher oxygen levels and a more stable ecosystem.

• Supports the Nitrogen Cycle: Regular dosing ensures a robust biological population, helping your aquarium handle sudden increases in fish load or waste.

• 100% Natural & Safe: Contains no harsh chemicals. It is completely safe for freshwater and saltwater fish, as well as live plants and invertebrates.

• 16 oz Economy Size: This professional volume treats up to 960 gallons (3,634 L), making it the most cost-effective way to maintain large display tanks or multiple setups.

When to Use Stress Zyme:

• Weekly Maintenance: Add every week to keep the gravel clean and the water polished.

• During Filter Changes: Use to replenish the beneficial bacteria that are lost when you rinse or replace filter cartridges.

• New Tank Setup: Works in tandem with API Quick Start to build a comprehensive biological foundation.

Dosing Instructions:

1. Shake Well: To ensure the live bacteria are well-mixed.

2. Standard Dose: Add 5 ml for every 10 gallons (38 L) of aquarium water weekly.

3. New Tanks: Dose at the same rate on days 1, 7, and 14 for a powerful biological kickstart.
