API Stress Zyme Freshwater & Saltwater

Introduction

API Stress Zyme is a biological aquarium conditioner designed to promote a clean, balanced, and healthy aquatic environment. It contains a concentrated blend of live beneficial bacteria that break down organic waste—including uneaten food, fish waste, and plant debris—helping to reduce ammonia, nitrites, and nitrates. Safe for both freshwater and saltwater systems, it supports biological filtration and improves water clarity.

Features

• Live Beneficial Bacteria – Contains millions of active bacteria that break down organic pollutants and help maintain water quality.

• Enhances Biological Filtration – Strengthens the tank’s natural filtration system by supporting the growth of helpful bacteria.

• Improves Water Clarity – Reduces water cloudiness caused by organic waste, resulting in a clearer and more visually appealing aquarium.

• Reduces Fish Stress – Helps create a healthier, more stable environment by minimizing harmful toxins.

• Dual Use – Suitable for both freshwater and saltwater aquariums, including reef and planted tanks.
