AES sells oversized "O" rings that can be placed around an airstone that
will keep it off the bottom. My airstone "manifold" is mounted on a hard
plastic plate to keep the stones away from the liner. Personally, I've never
heard of a stone vibrating a hole in a liner, but I suppose it IS a
possibility. Then again, because of lawsuits over very frivalous things, I
think people are thinking of everything that can possisbly go wrong and
trying to find ways to circumvent them.

Jan, This is the second post where you've stated air stones
vibrating a hole in the liner! What is going on here?
I have been using air stones for 9 years. No holes in the liner.
I've never heard of such a thing .... :O)

And Air pump, yes. A cheaply made air stone can be had using drip system
parts. Tubing, connectors and leaky tubing are similar in size to
aquarium
hoses, and even better suited to being outside. Also the leaking tubing
is
rubber and won't vibrate a hole into your liner like an air stone could.
Thus, if using an airstone, keep it away from the sides or bottom of a
liner pond. ~ jan

removing several plants noticed a subtle yet distinct odor that

anaerobic activity. My little pump just causes a trickle of a

so
I don't think I'm getting the oxygenation that I should have. So,
here's
my
question:

I'm assuming air stones are the answer, as well as a larger pump. How
and
what kind of air stones are to be used? Am I going to have to invest
in
some kind of air pump as well?
