Water flow rate

I have a 1200 gallon pond with Cichlids - Sorry no Koi.
We use a tetra cannister filter with an 1100 gph pump. The filter was
running very slow, so I cleaned the enire filter and it still ran slow. Then
I found a something jambed within the connection between the hose and
filter. When i removed this, I never saw so much water run thru the filter.
I'm actually wondering now if the water is running too fast. Should the
water be traveling thru the filter at the same or close to the same speed as
it enters? Seems it should in order to turnover the water volume. Boy this
guy is really flowing now.

The only reason for a filter to have a slow flow rate is to allow settlement
of solids. The bacteria will eat X pounds of ammonia and nitrite per hour,
and if the water moves slow, they just have a higher concentration coming
into them, but the end result is there will be enough bacteria to take care
of the ammonia and nitrites, regardless of flow rate. I prefer higher flow
rates over slower flow rates for most filters, but the veggie filter does
better with lower flow rates.

Which of the following series filters do you have? Biofilter or Pressure

I run a PF-3 @ 1200GPH on a 600 gal pond with no problems.

I use the PF-3 Bio Filter. Our pump is a Beckett W1150 with about 42" of
head. This does not include 8 to 10' of horizontal run. Water is delivered
via a 1" id pipe. If my calculations are correct I should be right at or
slightly above the 1000 gph in your chart with a filter designed to handle
twice the size of our pond.
