Bill,

I have a modest 10x4x4 pond and use an "Under Sink" type of filter. It uses
paper throw away cartridge style filters (I replace the filter material with
fiberfill bats cut to size) that are easily changed. Mine is connected to a
length of garden hose from the pump and back to the pond with garden hose.
The container for the filter can be mounted in more than one position,
upright being the first choice.
Something along those lines might work in your waterfall plumbing.
For my pond this filter provides all the external filtering with active
healthy fish, healthy plants, minor algae in the spring, clear water most of
the time.

What can I say?

The parts are slowly arriving for my DIY "Skippy" filter, but I'm still
not happy with the Flowerpot (10 gallons?) as a container. Sorry to
belabour this issue, but I could use some ideas. The flowerpot just looks
too flimsy, a little time in the sun and I fear it will suffer a serious
crack. (Although I did order a pump float switch just in case.) The other
issue is that the conical shape of the FP will not lend itself to tight
bulkhead fittings. I don't have enough space behind the waterfall to sit
a filter, so whatever I use it will have to be piped back to the
waterfall.

Perhaps I'll have to scrap the waterfall and sit a whiskey barrel in it's
place. although this is not my first choice. Your design advice would be
appreciated.

TIA

PS. The old commercial filter was put in Sunday and plugged solid by
yesterday!
