Torch coral

First photo is when the torch was added to my tank 2 weeks ago vs today. How come it seems to have lost that purplish color in the tentacles?
No changes in parameters everything is within reason nitrates 10 calcium 420 ph 8 alk 9 phosphates 0-0.25 (using api kit hard to tell)
I have only turned my light down. Using the AI blade through the mobius app on the high output growth setting reduced whites. Was running at 75% but turned it down 60%. The raised tank mounts are on the way currently just using the stock mounts for now. What can I do to bring that color back

More than likely a lighting issue

As an FYI, API doesn't work for phosphate it gives a range from zero to .25, and the next range is .25 to .5. I keep my phosphate at about .05 for example, which is impossible for the API tester to measure, its not accurate enough for our hobby. Get a salifert or hanna, hanna is really the most accurate of all for phosphate.

But regarding the colour change I agree with the above comment

I assume I need to give it less light?

Yea I’ve come to realize that test is kinda useless grabbing a salifert test when I can

More light will get you more color with torches, to a point.
I think the brown color is due to an overabundance of photosynthetic zooanthellae production, a reaction to low light conditions.

Oh so I need more light? I was worried it was bleaching cause where it sits in the sand bed is almost directly under the light. At the intensity in running it off all the research I’ve done about the par these lights put out (I don’t have a par meter) is around 100. I’ve read they need to be around 250 par?
