Oh heck yes! That's what we do here. Help. read our articles section on cycling a SW
tank. That'll explain what you'll be doing for those 3 months while you "get comfortable with the water quality". Getting comfortable with the water will continue as you begin to stock it with fish and inverts.
Tell us first if you can more about the lighting. That'll determine if you do fish only or reef/coral and fish and what types of corals.
I'd also guess that with your current level of knowldge about the hobby and your recent purchase, we can get you set up with fish by about July or August.
Well, kinda serious about that, depending on your ability to possible spend a bit more if needed and do some research. Will likely need a few new and inexpensive plumbing pcs at least.
You've come to the right place. We love projects and pictures, and you've got (or will have) both for us. C'mon, let's get started! Why aren't the pics up yet?? C'mon, c'mon!!
All that said, patience is the key to a successful hobby experience.
