SPS or photosysthesis Question

[woonming]

I don't think you can leave the lights on for 24 hrs a day. They also need rest period.

Some sps only extend their polpys to capture prey only when the lights are out.

Food in term of photoplankton and zooplankton are important to their growth as well as water quality.

As for the colour, it depend on your lighting and nutrient in the water.

If what you have is a brown coloured sps, then I don't think the colour will ever change.

Probably you can enhance the colour by using actinic lights.

Good luck.
