Mike,
Check the thread "Anyone interested in a group/power buy?" and look at the RO systems Fahz has. that power buy is ending soon and theirs some nice discounts there.
I used to have the same problems. It was very, very frustrating, not to forget to mention expensive. what I did was dial back to frags, (or fragments of corals, found through the club and the trade.) and focus on equiptment for a while.
It has really helped me to visit the setup of hobbiests in this club, talk, see what everyone is doing. In my little over a year being involved, my friends and family have noticed my massive strides forward. There is still more I can learn from others yet. Come to som meetings. buy a frag or 12. (slowly at first) turn some stuff around.
I would always move way to quickly. You will do better, as most will agree, by moving very slowly with your tank, until you get going. Even after you switch to RO, your rocks may contain phosphates that take years (or never) to work their way out. This change and even if only using ro, could take 2-4 months to take affect. I have heard, from some one in the group, nothing good happens fast in a reef tank. So, with that, I have multiple hobbies, so I am not always fiddling with everything. If it was up to me, I'd set it and forget it for a few days... but I can't. I have to check it daily.
Your always invited to my place to look around. I can give you a few lessons in what not to do.
