Fluval Biomax for Fluval Spec/Flex/Evo Aquariums | Suitable for Fluval Flex, Spec and Evo Aquariums.

Used these in the second chamber of our global flex tank. Much better with 2 filters running in the tank. Great quality and easy to clean for good maintenances. Helps to keep the tank crystal clean. We clean every few weeks in tank water. Fits in the foam cutout perfectly. Good value.

I have been using this product in my Fluval filter for years to keep my aquarium water healthy. Simply rinse the bag well under fresh tap water (about 30 seconds) and place it in your filter.
