Re: Filter Capacity ( Flow rates)

["Madan Subramanian" <madans at hathway_com>]

If your Power head or pump is rated at twice the capacity of your aquarium
ie.,
an aquarium of 30 gal volume and power head of 60gal/Hr. capacity and this
power head passes the aquarium water through a device, assume a UV
stabiliser, that does not progressively get dirty unlike a filter for
example.

Then in order to have 99.99% of your aquarium water pass through the device
it takes 4.6 hours.

In case of a power head pumping through a filter which progressively gets
dirty with time the time taken for 99.99% of the aquarium water to pass
through the filter is 6.375 hours as the flow rate decreases with respect to
time.

The more you know the more complicated it gets !!!!!.
