Maintain a healthy, clean aquarium by growing beneficial bacteria with the AquaClear BioMax Filter Insert. One of the most effective ways to maintain good water quality and keep your fish thriving is by seeding your aquarium with good bacteria. This bacteria breaks down harmful ammonia and nitrite from fish waste and other organic matter and starts the essential nitrogen cycle in your aquarium. Prepackaged in a mesh bag for easy installation, BioMax’s complex bio-ring pore structure allows beneficial, toxin-reducing bacteria to thrive, which in turn increases biological filtration efficiency by up to 30%. Exclusively designed to fit the AquaClear Mini CycleGuard Power Filter, Size 20, this BioMax filter insert is suitable for fresh and saltwater aquariums.
Biological filter media keeps the aquarium clean and healthy, maintains good water quality and keeps fish thriving.

Much cheaper here

I always check Chewy now before going to the local pet store....9 times out of 10 I will find it cheaper here. All of my fish died in the Arctic weather we had here in Texas, I tried all I could to keep them alive but was unable without any heat source. I will continue to buy here once I rebuild my tank in the future.

I would purchase this product at my local aquarium store, but Chewy's prices and availability could not be compared.
It does the job

It's a filter insert-it fits well and does the job of maintaining clear water.
Love the Aqua Clear Biomax Filter Insert

I have used the Aqua Clear Biomax filter insert for two years and love it. I do not change monthly because I use the sponge, carbon and ammonia inserts. I only change the Biomax filter insert every 4 months. I change one filter media per month. Keeps my aquarium fresh and clear. Even after water changes and cleaning it takes about 15 min for my 20gal tank to get clear again . Love this product.
Can't go wrong with biomax

Perfect size I bought this to go inside the S10 filter in the first chamber. I've used these for years and they last forever. everyone should run some of these it just in case you have to set up a new aquarium than you've got biological media ready to go.
