Why buy from Pond Planet?
API Stress Zyme contains live bacteria to consume sludge and reduce aquarium maintenance.
Stress Zyme adds beneficial bacteria to break down and consume organic matter to help keep the aquarium clean. The bacteria in Stress Zyme is uniquely suited to consume aquarium sludge, and keep the gravel clean.

These bacteria improve the development of the biological filter and help clean dirty aquariums. Making Stress Zyme a part of regular care assures an active biological filter, cleaner aquarium, healthier fish and good water quality.
To maintain a clean, healthy aquarium add 5ml per 38 litres of aquarium water weekly.
For new aquariums, to boost the biological filter add 10ml for every 38 litres of aquarium water for 3 weeks.
