API Stress Zyme - Freshwater and Saltwater Aquarium Cleaning Solution

Keeps freshwater and saltwater aquariums clean and reduces maintenance

Keeping an aquarium clean isn't just about what you can see. Fish waste, uneaten food, sludge and other organic debris can build up in gravel and around your aquarium, contributing to poor water conditions and putting extra pressure on your biological filter.

API Stress Zyme contains over 300 million live bacteria per teaspoonful to help break down sludge and organic debris naturally. Used regularly, it helps keep gravel and aquarium surfaces cleaner while supporting a strong biological filter and a healthy aquarium cycle.

Stress Zyme is suitable for freshwater and saltwater aquariums and is designed for weekly use to help reduce the amount of routine aquarium maintenance needed over time.

How to use API Stress Zyme

Shake well before use.

Add 5mL per 38L of aquarium water using the dosing cap.

For new aquariums or when boosting the biological filter, double the dose at start-up and continue using the product for an additional two weeks.

For established aquariums, use weekly to help maintain biological filtration and keep organic waste under control.

Wonderworld Tip

Think of Stress Zyme as helping with the jobs you can't always see. Keeping beneficial bacteria working in your aquarium can make it easier to stay on top of organic waste, but it isn't a substitute for regular maintenance. Good filtration, sensible feeding and regular water changes all work together to keep your aquarium healthy.
