The tank looks brand new, have you even had any algae on the glass yet? Typically, you would want to see some algae, but it looks like you simply left the lights on for too long during your cycling or had them on their highest intensity. You have to time the CUC right along with the correct light schedule to prevent what you have done. It is not too far gone. You can pull out everything, scrub, etc., but need to lower your intensity or length you are running the lights.
