Tamus,
Just of word of warning. When I first got into the learning of things...especially from this board...I obsessed on wanting to know more and more and more....MikeT was also correct in my relentless questioning. Once I got a taste, I needed more...I even had dreams about how I would build my ponds, waking up in the middle of night with some kind of revelation on pond filtration....
...believe me, I was sick!
But now I'm good...I'm at a point now where I just have to do.... It has been a most excellent learning experience thus far and I still feel like I'm in in pre-school. Don't worry, take your time, we got a lifetime to learning ahead...Good Luck.
