GBTA closing daily at 7pm?

[intermision]

Over the last few days my GBTA has closed up at roughly the same time everyday for about 1/2 hour. Then it opens up and looks great, and before it closes it looks healthy. Any ideas as to what could cause this?

Mine did exactly the same thing, it's just doing an internal water change IME.

Sounds reasonable. I'm not worried about it because he always opens back up. Mainly I was just curious.
