It sounds like you are definitely on the right path with this tank. Just imagine, you figured out all this without us. Just a few other things I noticed from your latest posts:

1. Can you have a small cabinet built to match your stand in which you can put extra equipment and even a top off tank? That;s what I am going to do on my new tank and I have seen a few others do something along the same lines.

2. Good move on the turbofloater. That should solve a lot of your nutrient problems.

3. You might want to reconsider the SCWD. Ask some folks here that have used them. There are some negatives with them. I've never run one but have seen the comments of people that have used them. I think most of them have moved on to Oceans Motions. If you are only going to be running FOWLR tank then it may not be necessary. The same thing applies to a lot of extra lights. Are you planning on moving up to a reef tank?

4. I assume there is no one taking care of your tank on the weekends. What are you doing about top off and feeding? I have the same issue with the tank I have in my office. Fortunately, I only live a few blocks from the office and I am usually in there on weekends to do water changes anyway.
