I bought the Laguna Powerjet Foam free fountain/pump this year. It's
basically a pump inside a plant basket, although I suspect a plant basket
would have more filter area. It's been running in the pond about three weeks
now, with mixed results. It seems to clog daily the last little while. Not
totally the pumps fault, as the neighbour's Honey Locust has dumped about 3"
of crap in the pond since I mucked it out at the start of the month. I'm
somewhat surprised, as the pump is sitting a good foot off the bottom. At
least I know it's got good suction. It's also got an annoying tendency to
fall over, with the suction and the weight of the large Bell fountain. But
they do provide screw holes in the bottom for some ballast, so I'll have to
find a suitable weight.

I finally hooked up the filter and waterfall today (plants have been
handling the Nitrates/Ammonia), but the water is getting a tad muddy. I
bought the pump/fountain to get away from the tiered fountain that kept
clogging with Algae and to get a bit more power for the waterfall. Seems I
might have a bit tooo much power (2400 gph), as the water barely touches the
rock of the waterfall before hitting the pond. The birds used to enjoy the
waterfall, but they don't seem to be into white water. Although I'm sure
it will settle down, once the filter gets a bit dirty.
