Is it possible to setup a no maintenance CO2 tank?

I’ve been out of the aquarium hobby for a while now. I love the process of creating and setting up a planted tank. But once it’s complete I get tiresome of the maintenance. I’m wondering if it’s possible to setup a tank that requires little to no maintenance, no water changes or cleaning algae. I don’t mind trimming on occasion.

I would have it fishless for this reason (I could add fish food for ammonia?) and CO2 + light on a timer for plant growth.

Is this possible? Am I missing anything?
