How much water can one sponge filter a day?

The amount of water a sponge filter can filter in a day varies based on its size, the type of sponge used, and the flow rate of the pump. Generally, a sponge filter can process anywhere from a few gallons to over 100 gallons of water daily, with larger filters capable of handling more. Proper maintenance, such as regular cleaning of the sponge, can also enhance its efficiency.
