Product Information
Fluval Biological Aquarium Cleaner is ideal to make sure that your aquarium is perfectly clean and healthy.
It cleans gravel, filters and all types of décor, and eradicates organic matter such as fish waste and plant debris. This makes the Biological Aquarium Cleaner ideal for heavily populated tanks, which produce a lot of waste, which of course turns to ammonia, causing all kinds of health problems.

- For general maintenance / waste build up Fluval recommend 5ml per 37.8 litres.
Key Features:
- Perfect for new set ups and maintenance.
- Great for densely populated aquariums, goldfish and cichlids.
- Reduces the amount of organic waste matter.
- Safe for fresh and salt water aquariums.
