Hi Mr X thanks for the reply,
I have a daylight fixture over the refugium but the fixture also serves the blue over the DT (the sump is located behind the DT)
I will turn them all off from now on during the night and leave the moonlights on.
Is it natural for the goniapora to shrink when the lights are switch from day to night? It doesn't last for long. I'm guessing this is a natural defence
Thanks for your valid input.
