Fluval SPEC Biomax - 2.1 Ounces (3 Pack)

I needed this product to replace the one that I had in my fluval flex aquarium. It must work really well because I have had the aquarium for 6 years and have never changed the water! And the aquarium looks great, the fishies and shrimpies are happy, and so am I.

I’ve used Biomax since getting my first Fluval aquarium. It’s easy to put in the foam block. The water staysclear.

This is the Biomax that fits in our filter's foam block.

Product is what it is, change out every two or three months, this pack of three will last half a year, so price is well worth it. As long as they rinse out white they are good, when they turn color then changeout is required. Good product!

With the foam , charcoal and these beads it keeps your aquarium clear !

Works great. Easy to use. Clean tank well

This Biomax media is the correct replacement for the Flex 32.5 according to the Fluval website, however the Flex 32.5 is not listed on the box as being compatible. I installed these a couple weeks ago and they seem to be working great so far. They are little different/smaller than the ones that came with the Flex 32.5 though.

Perfect for my 15 gallon Fluval Flex aquarium. I like that it's a 3-pack so I have some ahead.
