Worth the switch
Best priced for weight and quality. My large messy red ear slider needed these. They cut down on maintenance by keeping the water clear longer. Bags can be washed out making them last much longer then the throw away skinny filters.

Using one bag for every 60 gallons of water proved to be the sweet spot for optimal results.
These little bags of activated carbon charcoal worked wonders in my aquarium. Within a short period, they effectively removed the water’s unpleasant odor, colors, and organic pollutants. The water became crystal clear, making my fish swim happily and visibly content. I was thrilled to see that the product lived up to its claims.One thing I learned while using these filter bags is not to overload them. Using one bag for every 60 gallons of water proved to be the sweet spot for optimal results.
