Fluval U Underwater Filter BioMax, Replacement Aquarium Filter Media, A495

This replaced my cartridge base media from a Betta 5.5 gallon filter. Its easy to clean just dunk it in old tank water and move around.

Works great.

Really like the small size media. Dont have anything else to say. These reviews require too many words. That is all.

Bought it with filters. Works great.

I got this for my Fluval U2 underwater filter, it works great. Will get again, overall happy with the item.

For the price, not worth it

Helps keep my fish tank water in perfect condition. Crystal clear water and healthy fish. Does what its supposed to. I wish it was a little cheaper.

Cant beat the price, i keep them on hand & use them on my many hang on back filters, & my canister filters

It comes already in a mesh bag, so that is nice. I was worried I would have had to go out an buy one, but it comes included. There are nice and porous. Good for my aquarium

This is a very good price for this product. I would recommend this product and will by again in the future.
