Lighting period zoa tank

[andrenym00]

I have a 29 gallon biocube with led lights 2-8k/453nm 1-453nm Panorama . I keep the 453nm on from 2:30pm to 11:30 pm and the 50/50 on from 4pm to 10pm. Is this lighting schedule enough? I have mainly zoas and florida ricordea. Should I increase lighting time? Thx

How long have you had them under this light schedule? How does everything look?

I run a late-day schedule like that too with actinics on at 1pm and off at 11pm. The main lights come on at 2pm and go off at 10pm. If your zoas are healthy and look the way they are supposed to, keep the lighting period you have. If they change color from when you got them, give them a little bit more light - 6 hours of main lights seems a little short for me - but if they are fine no reason to change it. Even though zoas aren't known for their high minimum lighting requirements and will live under almost any light, they love light just as much as any SPS and will get their best colors under lighting that would bleach most other corals.
