Zoas closing at a specific time everyday

[805lopez1989]

Hey guys I want to get a little bit to help my zoanthids Are closing up every day right around 12 to about 3:00 p.m. I don't know why my calcium is around 4:00 my alkalinity is a 9 point to my magnesium is that 14:00 My nitrates are about 5. I have check my lighting and I did the specs to the BRS SpecsI really don't know what to do I am dosing in a 24 hour. At those very small amount every hour

That is odd. Is it one colony or several throughout the tank?
Does your flow change in the day?

 

[ZoWhat]

What's your lighting setting during that time period?

Could also be a pest coming out picking on them during thst time....

I’ve seen this happen many times and always found it was the lighting.

No worries, they just need a break from the intense light.

Its all my zoas I know its odd as far as current it does not change it only slows down at night as far as lighting goes im using 2 hydra 26 il post a picture of my settings

Lighting. Try lowering the intensity a bit and see if that helps

Pretty sure everyone nailed it with the lighting. 12-3 is when most run their highest light.

These are my setting they are the BRS settings for lps I had it at sps settings so I turned them down so I should just leave it or still turn them down a bit I think it has to do with lighting for sure ill try bringing it down a little more

Depends, if it‘s a mixed tank with sps/lps just leave it, the zoa‘s will adapt.
