Pressure treating weakens lumber, but I don't
know how much. Maybe you can find statistics
on the web.

The chemicals injected into the wood are toxic.
I think PT lumber contains both insecticides and
fungicides. Bad news for delicate critters. Heck,
bad news for humans .

"Fresh" PT lumber from the store is practically
dripping wet with these chemicals. If the lumbers
air dries for a few months, it will pose less risk.

Personally, I would not use PT lumber anywhere
near an aquarium.
