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,

tia.
