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.

Purchased as spares all is in order

Very good product always use these

Does what its made for

Flu will always make great products bought this to actually go in a bio master filter by OASE. Two bags of this fits perfectly in the 100 internal filter in one of the baskets gives much better volume of filtration media than foam

Does wonders , good product keeps water healthy for fish, I use a lot of these in my Aquaclear 70.

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.
