The amount of water a sponge filter can handle in one minute varies based on the specific model and its design. However, a typical sponge filter in a home aquarium generally has a flow rate ranging from about 1 to 3 quarts per minute.
Given the options you provided:
- 1 quart
- 2 quarts
- 3 quarts
- 4 quarts
The most common answer would likely be 2 quarts or 3 quarts. However, 3 quarts is often at the higher end for many sponge filters, so it's reasonable to choose 3 quarts if you are looking for a higher capacity example.
