I am about to purchase a 150 marineland dual intake. Not my first saltwater tank. I have a 30 gallon salt set up a couple months ago. I also have been keeping fish (ponds, 125, and many other smaller tanks) for about 6 years. I want to upgrade and put it parallel to my fresh water 125 I think it would look sick. I need to know what equipment I need for a tank that size. Every step of the way. And on a budget. I want it to have a lot of coral and fish(reef tank). I need to know what fish to buy and equipment. Please help me. I will post constantly to update every step of the way.
