That looks really nice...and like you said, with the sand, changing it out regularly is key.
I don't recommend the use of sand to people because I assure you, you are in the 1% minority that is willing to change it out regularly. I can't advocate something that isn't practical for most people to want to do. Kudos for keeping up with that though! Loose substrate does look very nice when done with rocks and plants and whatnot, there's no denying that...
