I noticed at least half of my zoa colonies are open during the initial lighting period of the day but later in the day they close. Zoas like my bam-bams and eagle eyes, radioactive dragon eyes are closing during the later part of the day. I also am fighting cyano on some of the them, but they are getting really good flow. If I turn my gyres up any more the sand bed starts going nuts so I do not think it is a flow issue. My lights are two Radion G6 pros over a two foot deep tank, lighting intensity around 80%
I hate to change too much too quickly, the majority the tank looks excellent but I am starting to lose some of my zoas that I have had a long time.
