Help with refining details
 

I'm planning a upper level pond - approx. 6ft x 4ft, various depths
with deepest point probably being 1.5 feet. This upper pond will
basically serve as the head pool for the cascading stream. The stream
will have a series of small falls (this is a natural downward slope)
and will be approx. 20 ft in length and 3ft wide. This will end in
bigger falls to the larger pond which is about 12ft x 18ft and 2.5ft
deep.

I plan to use a Sequence pump and a 100 gallon stock tank to make a
"Skippy" biofilter.

I am having problems with the plumbing schematic and calculating
friction loss. The pump will have to push water up an incline slope
to the highest discharge point at the biofilter. I am guesstimating
the head at 15ft. Most piping will be a straight line run except for
elbows into the biofilter and two on the biofilter discharge to the
small pond.

What size Sequence pump would you recommend? 2" diameter pipe? Will
it be ok to place the biofilter parallel to the top pond? How do you
house your external pumps? Links, advice, etc. appreciated.

Thanks in advance.

The amount of head at 15 foot would just about stop flow on all the Sequence
pumps. If you have 15 foot vertical plus the length of pipe and elbows,
then I would recommend you look at one of the medium head pumps. Sequence
makes a high speed pump, but the electrical draw is pretty high. Aquatic
Eco has an RK2 pump at 1/2 horse that draws 4.3 amps that would give you
about 3600 gallons per hour. They also have Wave II pumps that could meet
your needs.
