Re: Subject: [GSAS-Member] UV light to control algae, ecological consequences of using bogwood

[welenofsky@comcast.net]

Hi John:

I've used wood from the beach before. You can find stuff that is as dense as 
bogwood sometimes, and will sink. It worked fine, but I took it out later, as 
some hair algae was growing in a crevice on the wood. You can soak the wood, so 
that it will be waterlogged. One thing to watch for though, is if the wood gets 
stinky. I had some smelly wood in my outdoor holding tank that killed the fish. 
I'm not sure what that is called, maybe anaerobic bacteria? 

I've also wondered what the consequences are of buying bog wood to the natural 
environment. I would hate to be contributing to something that ruins a habitat.
