I'm 29 years old and addicted to saltwater reefs!!!!! I have a 40 gallon nano reef/marine system. I got into the hobby about a year and a half two years ago. really l. and learning a lot of these forums lately. the past six months ive been real doing a lot more research. it only took 2 years and two bio-overloads and about 800 dollars worth of fish to fig, out I didn't know what I was doing and my friend the so called expert didn't either. so if u wanna know what not to do wrong just ask ive done it all!!! lol
