Wanting to set up a 90 Gallon

[katguevara]

Hi!,

I currently have a 90 gallon tank that isn't drilled for a sump. I'm wondering if I'm able to use this to set up as a saltwater tank? If so, can you guys give me some suggestions on equipment for a good set up. I'm new to this so please bare with me! I can go to big Al's and ask, but I'm afraid that they are going to give me things that I don't need. All suggestions are welcome! Thanks!
