#25: What's Happening - Testing The Anodes

Maintaining the Giant Ocean Tank, which has been on exhibit since 1969 can often at times be challenging. With a total of 67 windows, only a few have had to be replaced. The window frames are protected from corrosion with the use of an anode. An anode is a sacrificial corrosion device. Once installed they require a weekly cleaning, and quarterly testing.

Testing the anodes requires a team of at least two people. The windows are numbered 1 to 67. A diver places the probe tip on the window frame.

On the surface the information is gathered and recorded for each window.
