Fluval Biological Aquarium Cleaner breaks down organic waste like fish debris and uneaten food that builds up on filters, gravel, and ornaments.
Fluval Biological Aquarium Cleaner reduces unsafe organic matter (fish waste, decaying leaves, uneaten food, etc.) that regularly gather on filters, gravel, ornaments and other surfaces.
Freshwater and marine aquariums.
Fluval recommend using it together with Fluval Biological Enhancer (Cycle). That is not upselling: breaking organic waste down releases ammonia, and the enhancer is what keeps that from becoming a spike.
Fluval rate the 1 fl oz / 30 ml bottle to treat up to 30 US gallons / 113 litres in total.
It works on the organic matter that accumulates where you cannot easily reach it — in the filter, in the gravel, under ornaments. The bacteria in it break that down so it does not sit there decaying.
Best used on a heavily stocked tank, on a new set-up, and as part of a routine rather than as a rescue. Follow the bottle’s own dose rate for your tank volume, and keep testing ammonia while a backlog of waste is being processed.
Every batch we dispatch carries a minimum of 6 months’ remaining shelf life. Store this product in a cool, dry place away from direct sunlight, with the cap or inner foil closed tightly after each use.
