Customize Navigation bar

I’ve searched through the forums heere and haven’t quite found the anser I need. I want to customize the top navigation toolbar where the Home link will take users to an alternate site. In other words, I’d like to change the URL for that Home tab. The suggestions I’ve found here have recommended using the Menu customization tool. However, the problem with that method is while I can create whatever links I want and arrange them in whatever order I want, it creates a second navigation area at the top of the page that looks redundant in my opinion and don’t really care to have. Furthermore, The Home link on the navigation bar is still not sending site visitors to the page where I want to send them which kind of defeats the point. Any ideas? Thanks for the assist.

By the way, the site address is: tetu.salighthouse.org
