Well Lionfish, I can't speak for everyone, but I, too, was somewhat nervous starting my tank (which has been up and running for several months). For me, it's the thought that, if something goes wrong anywhere along the way, a living creature could suffer....or worse. That's a big responsibility, and one that I, personally, do not take lightly.
That said, I have found the whole process to be very rewarding, and a real learning experience. I'm sure you will find it to be the same.
Good luck!:yes:
