Can the apex work with an infrared sensor like the Tunze, or is your only option a float valve?

only float switch, yes it can be a problem if float switch failed but it can support multiple so i have multiple float switch to monitor my tank.

Also it is much cheaper to replace the pump if it failed rather the tunze one. However, cost you more for initial set up.
