Question, re: SPS Polyp Extension

[Aquattro]

Drew, I get great extension during the day, always have, not sure why. However, at night, I see a lot more, especially with the axial polps (tips). Night time feeding is the reason for the evening activities, but daytime seems to be dependant on some (to me) unknown factor. The night time stuff won't be a result of zeo activity, corals have been doing this way longer than zeo's been around.
