Can I use the pressure treated wood as sort of moulding on the edge of the
pond? Or will it poison fish if it comes in contact with water?

It will poison the fish.

Google pressure treated wood and read up on
what the wood is treated with. In the USA,
the old wood was treated with arsenic (or a
type thereof). I don't know what the new
treated wood is treated with, but just because it
is (presumably) safe for plants and humans
doesn't make it necessarily safe for fish.

Also remember that even if the wood is
above the pond water level, rain will wash
any contaminants into the water.

Pressure treated wood is, in fact, highly toxic to humans. Just read the
warnings about working with it. otoh, heavy metals are not very toxic to
fish.

otth, copper is toxic to the invertebrates.

I'm not convinced that cedar is any safer than PT lumber - the dust is just
as unsafe to breath as the sawdust from PT lumber.

Completely untreated wood doesn't rot very quickly below the water line -
the problem tends to be right at the air-water interface. So, for anything
that will be submerged pine is plenty good enough. For edging, you're
probably best to use an untreated wood, and plan to replace it every 2 or 3
years.

Derek, I was referring to the new pressure
treated wood. I know the older stuff was
treated with arsenic. Not the newer wood.

Something like TREX (artificial deck wood) might give you permanent
material. Haven't checked about leaching from it.

the entire face of the veggie filter of my pond is cedar ... the water runs down it.
algae and now moss are growing on it. the fish are fine. of course cypress is just
the best. Ingrid

They're still toxic to humans - you just have to read the warnings about
working with them. Note, also, that that article mentions the copper
content has been increased. Even copper isn't good for us internally, and
it's deadly to the invertebrates in the pond.

We've been using a borate treatment - as the Taunton article says, it's
pretty safe, but you'd still want to be really, really, careful about
cutting wood that has been treated with it. Still, you shouldn't use a
power saw on wood without a mask - sawdust from the most innocuous wood
isn't good for you, either.

=========================
We read somewhere not to BURN unwanted treated wood as it releases toxic
waste into the atmosphere. But then it releases toxins when buried so we
shouldn't bury it - I wonder how we're supposed to dispose of it?!?!?!

When I researched Trex for a cover for a large (12' x 6') filter I was
dismayed to find it not recommeded for continuous high humidity. I don't
recall if it said anything about ground contact, you might want to check.
