Welcome! Glad you joined. With your freshwater background (I come from freshwater originally too) as well as all your planning, you will have many successes!!
Have you considered starting your build thread? I found its a great place to document my tank's evolution for myself. I wish I had started thread during planning stages like where you are now. I started tank first then joined, so I'm still finding myself going back collecting pictures & updating historically as well as current state. Once you create your first post in your thread and link it to your account, they will give you build badge (look left, under my ID)
This is a good reference book type online article I still review:
