    Has anyone ever heard of this type of airstone / gadget?

    "I have a plastic air stone which is adjustable. It is a series of
    plates that may be tightened or loosened to control the size of the
    bubbles. It makes a very little hissing noise when it is set for very
    tiny bubbles. Certainly as loud/quiet as the whisper filter on the
    tank."

    Of course

    Most popular with bare quarantine, commercial tanks, Asian Discus operations often sport a few as inexplicable decor.

    The unititated seeing these bright TOYS, can be forgiven for thinking so.

    Low airpump backpressure. Easily cleaned. Durable.
    All plastic, easily sterilised.

    Not that available in SA.
    Here's a pic of ONE type
