Okay well, I had plan's to do a planted tank, but for some reason my mom all of a sudden want's me to do a SW tank

. But im not loaded with 2000 bucks for a 75G right now, and she agreed to pay for quite a bit of a BioCube. Currently im reading my reef book and I will probably finish it up this weekend. Basically my only questions are, about what coral's I can do with 36 watt compact acintic, and a 36 watt 10,000k compact bulb. I will be upgrading to Metal Halides/T5HO's in the next couple months but I want to find some beginner coral's to start myself out on. I probably will read up to this part in my book this weekend but I'd rather hear from people who have experience. It will all hopefully go well, and I will get to start a 55/75G reef later in the year.
Another question I had was. RO/DI water... I don't really wanna buy a RO/DI system so what else can I use? I hear tap water will cause a nasty bloom of the Brown algea. Yuck XP.. Any info would be helpful!
Thanks
