    Crew comments that the toilet flush water is finally looking clear rather than green!

    Miscellaneous: Have not had time to measure levelness of the shower floor. But it's definitely not level. Noticed that there is no power to the outlets in the shower room. Seems they are not connected. Just thought we'd let you know.
