WHAT DOES YOUR REEFING AREA LOOK LIKE BETWEEN MAINTENANCE SESSIONS?

  • Clean and tidy—everything gets put away

    Votes: 10 45.5%

  • Mostly cleaned up, but a few tools stay out

    Votes: 6 27.3%

  • Organized chaos—I know where everything is

    Votes: 3 13.6%

  • Enter at your own risk! Buckets, hoses, and towels are basically permanent fixtures

    Votes: 1 4.5%

  • It depends on where I am in the maintenance cycle...

    Votes: 1 4.5%

  • The tsunami hit. Hard.
