Review on Enhance Your Water Quality with OUFISH Aquarium Bio Balls: Ceramic Biological Filtration Rings for Fish Tanks and Ponds! by Paul Williams

I saw how well this product was rated and I ordered it for my tail tank just based on the pictures. I have three different aquarium filters for my 10 gallon fish tank and assumed it would fit one of the filters. Imagine my surprise when a HUGE bag arrived that didn't fit in any of these filters. I went back online and read the product reviews and immediately saw my mistake as the sizes are listed in the reviews and not in the product description where I thought they should be. It really didn't matter, the packaging had a big hole which made the product unusable for me. Due to COVID-19 restrictions, returns were not possible so I threw everything away and bought a completely different product. Lesson learned. If you don't have a HUGE filter for this product, DO NOT buy it.
