Yes, the water has cleared up miraculously after adding the DE. I definitely recommend it.
The start-up guys told me to wait two weeks to add salt. While they are telling me this I'm remembering what I've read in my manuals and here and I'm thinking "it's going to be 4 weeks before salt goes inot THIS pool". I mean what's 2 more weeks when my interior surface could be conpromised. I've got my water balanced the way I want it and that's not a lot of time. I really can't wait to feel the salt water in the pool but I will.
Here are some final pics after we are officially done (with pool build, still got a lot of landscaping to do).
