Need some advice. I'm new to reef aquariums and am getting ready to buy my first reef tank. I've had a freshwater tank for years and finally decided that I wanted to switch to saltwater. I've been doing a lot of research and have finally got to the point of starting to look for equipment. My initial thoughts were to get a 36x24x24 (~90 gallon) tank. But after visiting some local shops I was leaning towards a 60x24x24 tank (~160 gallons). After thinking about it I'm concerned that the larger tank may be too much for a newbie. Any advice would be greatly appreciated.
