Now this is really complicated -- I suspect only this forum could answer it ;)

Actually, that may be true, since lots of people here may in fact use one.

How do I hold it down?

In one tank I have a rock on it -- that seems to work. In the other I have it suck partly under some driftwood, but bubbles get trapped and come out as very large bubbles at times.

So I was just curious what others do.

Attach a suction cup to the CO2 line before the limewood stone and place it anywhere near a good current source.

Hey -- that worked!
I drilled a small whole in the other end (offset to miss the whole that goes through it), shoved a plastic tube joiner in, put 1/2" piece of tube on it and put a suction cup on each end -- works really well.
Thanks for the suggestion.
