I have used the product for many years. I never have any complaints. Only one minor issue. When filling the Bio Bag cut a small hole in the charcoal package to avoid spillage. This product does what it is designed for filtering aquarium fresh water.

price wise
The largest amount I can usually get in a store is 8 I have a lot of fish so this size and cost keeps money in my pocket. I was thrilled to see what I could get from Amazon and will continually order from them.
