Concept built us an all in one (2 sections) ATO and mixing station. It's got 2 pipes with gates ( don't know the exact plumbing term).that you open and close depending if you want fresh or salt water going into the tank. It was not super expensive, looks great, and works perfectly. But it's not acrylic. They also put it on a stand so it's off the ground and my son can store his salt pails etc below it.
