Do you have any moon lights? I noticed that before I installed my moon lights when the first row of blues the fish would startle but after I put in the moon lights it was much less of a shock.

No, not yet. What colours are your moon light? white, blue or red?

Blue.

Thanks Greg. Will add two Mean Well with a few blue LEDs to dim it down to zero and add a few moon lights.

What would be purpose of using a different color?

I think sunlight has multicolor.
