Powerhead "Night Mode"

[Oscar]

I have been setting my Vortech20 to night mode as my actinics shut off at 9:00pm. Sleep mode ends 10 hours later at 7:00am.

During this time my 2 clowns are definitely in sleep mode and slowly start to perk up after the room lights come on and after the Vortech comes back to full setting. During their sleep time they are definitely using less oxygen due to less movement.

But I might try turning off the sleep mode for a few days and see if there is a difference in their response. I have very little in corals at the moment to judge their response.
