UGF's? yay or nay?
 

are you for them or against them? I have read a lot of arguments, but are there are some styles out there that seem better then others.

There was a recent thread (March or April 2011):
"Undergravel filters are not bad" that goes through the pros and cons. That might be limiting the response to your post!

I'd recommend searching through that thread to read specifics.

ok, thanks:-). is that in this section or a different forum?

Here is the link:

It's a pretty good discussion!
