Hi,

I want to have a vigorous "air cuirtain" at a depth of approx 1.5 metres in
an aquarium. Can anyone recommend an air pump that can deliver this? I have
tried a copuple but at depth they give out a pitiful amount of bubbles!

I have posted to rec.ponds as I suspect I might need something designed for
KOI ponds to deliver what I'm after,

Actually, the sal****er aquarium NGs would have been fine. Wooden
protein skimmer airstones give a tremendous amount of back pressure in
typically 2-3' tall skimmers so anything that can run a big skimmer is
also suitable for your application.

Try a TetraTec Deep Water series, or a Coralife Luft pump (used to be
the Tetra Luft pump). Schego pumps are also highly regarded by the reef
crowd but seem to be mostly for sale in the UK. I have used a TetraTec
pump and got very good results on the skimmer I was running without too
much noise.

http://www.elmersaquarium.com/h111_t...c_air_pump.htm gives a chart
of airstones the TetraTek will run at depth. The Luft pump comes in one
large size with a rheostat.
