API Stress Zyme 8 oz

The Biological Secret to a Low-Maintenance Tank

A clean-looking aquarium isn't always a healthy one. Over time, fish waste, uneaten food, and decaying plant leaves settle into your gravel and filter, creating a "sludge" that can suffocate your biological filter. API Stress Zyme introduces over 300 million live bacteria per teaspoon to specifically target and digest this organic debris, keeping your tank biologically clean from the inside out.

Why Stress Zyme is a Hobbyist Favorite:

• Natural Sludge Destroyer: It effectively "vacuums" the areas you can’t reach, breaking down organic matter in the substrate and deep inside your filter media.

• Extends Filter Life: By consuming the "gunk" that clogs filter pads, Stress Zyme allows for better water flow and less frequent mechanical filter cleaning.

• Optimizes Oxygen Levels: Decaying waste consumes oxygen. By accelerating the breakdown of debris, Stress Zyme ensures more dissolved oxygen is available for your fish.

• Proven Stability: Regular use builds a robust biological defense, making your aquarium much less likely to suffer from cloudy water or "mini-cycles" after a cleaning.

• Safety First: 100% natural formula. It is safe for all freshwater and saltwater fish, as well as live plants, corals, and invertebrates like shrimp and snails.

The "Hobbyist Choice" 8 oz Size:

The 8 oz bottle is perfectly scaled for medium-sized systems:

• Generous Capacity: Treats up to 470 gallons (1,779 L) of water.

• Monthly Maintenance: Provides several months of weekly dosing for a standard 29-gallon tank.

• Essential Post-Treatment: Ideal for replenishing beneficial bacteria after a course of medication has been completed.

Dosing Instructions:

1. Shake Well: To ensure the live bacteria are active and distributed.

2. Weekly Maintenance: Add 5 ml for every 10 gallons (38 L) of aquarium water.

3. For New Tanks: Dose on days 1, 7, and 14 to prevent sludge from ever taking hold.

4. Pro-Tip: Use in combination with API Stress Coat during water changes; while Stress Coat neutralizes the toxins in the water, Stress Zyme cleans the physical environment.
