Well maybe people should realize than that not everyone has a lot of experience with this program and that maybe it would be nice to answer a curious person's "dumb" question. I looked around the posts here but didn't really see any good answer to my question which is why I posted to start with. Just a polite informative reply is all I wanted just like the one Wizwad left. Also if you look at the information about the program on the official site there isn't a good description of what goes on in the tank. Also the screen shots page only shows one good size picture. I was hoping for a few more screens of the tank in action maybe with different setups and such. For someone that knows nothing about the program those are major selling points. But it's good to see that there are a few people paying attention here even if I did have to post a negative to get a positive. Hey, I tried to do it nicely.
