API Bio-Chem Zorb Filter Media Customer Reviews

Margaret, Waupun WI on 2016/01/19
Great product

Have used this product for years. Makes my aquarium water very clear. Really works!

Fish Filters.

I have 5 big fish tanks that are up and running. I have beautiful fish that my husband and I take care of. A LOT of work, but worth it. I had ordered $76.21 worth of aquarium filters for Fluval filters, Aqueon overflow filters, API filter media system (A lot of replacement filters for maintenance). That night my husband and I went to two other stores to compare prices on everything I bought and I was SHOCKED how much money I SAVED. Each store, I saved $65.00 on the same EXACT brand and quantity. I will always get my fish supplies now at Pet Mountain. Thank You. Robin

The best with the best

The best filter media (carbon) with the best filter equals clean tanks. If you do not own a Filstar Rena Canister the media fits other canister filters.

The best

I have tried everything, but now I will never buy anything but bio-chem sorb because it is the best!

Makes the water nice and clear

This is the first aquarium I've had where the water barely even has that "aquarium" smell. Nice and clear water. One pouch lasts about 1 month in my 55 gal freshwater.
