The "vacs" that work with water pressure, either hose or pump, are a waste
of time and money. They're cumbersome, messy and the vacuuming takes
FOREVER.
When I can afford it, I may invest in an electric water vacuum cleaner.
Mean-time I use a large extending triangular fish net with fine mesh which
does the job far more efficiently than the hose vac. However, it does cause
wear on the netting (scraping the bottom). Cost-effective PROVIDED you can
get one at the "right" price - Lidl (UK store similar to Walmart) had them a
while back at about £3 (versus £20 in the fish store) - and so far it's
lasted 2 years and counting.
The hose water vac cost me about £28 and is a total waste of dosh,
especially as the neoprene O rings perished after 18 months. They are also
expensive to replace (if you can source them).
My pond is similar to yours ...I've about 800 gallons (Imperial, not US
gallons).

I've been leafing through my Drs Foste and Smith water gardens supply
catalog, and I see a couple things like a pond leaf eater and pond mini
vac that work by attaching to a garden hose...has anyone tried these and
do they work? I've got about a 1,000 gallon pond and I need to get some
leaves off the bottom...
