water volume

I would have to agree that having a larger sump would add to the water volume and therefore let you have more fish. The larger the filter the more bad stuff it can hold in there and clean. Therefore giving more clean water to your tank daily.

Yup. that and they start killing each other for space. That also tell you your tank is full, even if you are under the "inches of fish" rule
