read read read read read read and I emphasis again, READ! About a year ago I was in the same situation as you, getting the same stuff. I mustered up some patience, read everyday, and now I feel completely confident in all of my recent decisions, and instead of all of that stuff that I was originally planning on getting like you are, I used the extra time to save and research and I ended up ordering that same light but the 2x65w double strip version, a 2x18w coralife t5, an xP3, powersand special m and ASA II, pressurized CO2, ADA ferts, Manzanita, and a 75p ADA tank. I would not be nearly as satisfied with what out came out my scape had I not taken extra time to increase my budget and learn exactly how everything workss and why it's necessary.
Let me tell you, I was in the EXACT situation and state of mind that you're in right now, and with time, patience, learning, and reading, I realized that there was sosososososo much more to it all, and that all the intricacies really really are completely necessary. Good luck, and TAKE YOUR TIME, there's nothing worse than ordering something, finding out you wanted something better or different, and not being able to return it. This is an extensive hobby, and if you give it a great effort, you'll love the great results, but if you rush it, you'll find you and your wallet in a load of hurt.
Take some time to view the photo album and see what people do with their money, and view the results they get with the effort they put in. Don't be afraid to ask questions, and USE THE SEARCH function, it's your best friend for researching! I spend half my life on it, lol
Good luck, and have fun
thats my 2¢
