I'm no expert, but I think a lot of people have trouble with their first tanks because they cut corners to save money and fail to do things right. But by doing so, you only increase the cost in the long run. I have just been very fortunate. I've been lucky to have a great LFS near by. Don't get me wrong, I have made plenty newbie mistakes.......damsels........trying to intorduce anemones too soon.......trying to mantain more difficult coral. It has been an experience that my kids and I have greatly enjoyed. If I could afford a bigger tank, I would have already upgraded. I want a 240 gallonor larger. Lots of money though.
