Weekly to reduce aquarium maintenance and maintain a strong biological filter

MARINE STRESS ZYME adds beneficial bacteria to break down and consume organic matter to help keep the aquarium clean.

The bacteria in MARINE STRESS ZYME breaks down organic compounds that cause dangerous conditions such as ammonia and nitrite poisoning and low oxygen levels.

These bacteria improve the development of the biological filter and help clean a dirty aquarium.

Making MARINE STRESS ZYME a part of regular care ensures an active biological filter, cleaner aquarium, healthier fish and good water quality.

  • Treats: 5 ml treats 38 litres

Add 5ml per 10 U.S. gallons (38L) weekly. For new aquariums, and when adding live rock, to boost the biological filter: double the dose, use at start-up, and for additional two weeks.
