Aquarium Bio Balls Fish Tank Pond Bio Filter Media Ceramic Biological Filtration Rings with Mesh Bag

All I have to say is Wow,AWESOME PRODUCT,Thanks to Bio-Balls I have never had a cleaner fish aquarium.Since I switched to this products my tank has never looked better,and one box fills up one big tray and they are also reusable .If you are looking for an awesome product at an awesome price buy this product.I guarantee you and your fish will not be disappointed.But if this bag can include more kind of other filters media, that will be even better.

This 5 in 1 filter media is great media I have used. I have 2 filter both side in my tank . One side I put 5in1 , another side I put 6in 1 filter media. Their ingredient different which make my 50 gallon fish tank so clean, and last for long time. I am so glad those filter media works well for me.Very recommended!!

Purchased 12 in 1 filter material package. Come with powder cause of material composition and shipping reason which is normal. After I clean it and put in my fish tank the filter material is very stable and nice.I have use it for a while which works still very well.

These are bigger than I thought. Which is a good thing as I plan to use them in one of the trays of a canister filter. Other than being bigger than expected the product looks exactly like the picture and comes with a nice zipper bag. Will buy again in the future when it comes time to replace.

I saw how highly rated this product was and ordered it for my betta tank just by the photos. I have three different aquarium filters for my 10 gallon tank and assumed it would fit one of the filters. Imagine my surprise when the HUGE bag arrived and fit none of these filters. I went back online and read the product reviews and immediately saw my mistake when the dimensions are provided by reading the reviews instead of in the product description which is where I would assume they would be. It really didn't matter, the bag came in with a large hole making the product useless to me. With COVID-19 restrictions in place, returns were impossible so I threw the whole thing out and purchased a completely different product. Lesson learned. Unless you have a HUGE filter to house this product, DON'T buy it.

Very good stuff. It fits my filter perfectly. Love the bag has zipper on it, I can open the bag and clean each of the ball. And the black ball even has filter sponge in it. Love it!

They work really well, but they are kind of big so if you have a smaller hob, you won't be able to fit many in them.

Great aquarium media! Lots of different media in one zipped bag, cleared my cloudy tank in less than one week. Highly recommended for your fish tank.
