Bleached spot

Recently noticed a bleached spot on my squamosa clam too mush light or something else?

it’s prolly too much light. Move it to a lower spot. If that’s monti cap next to it then it’s prolly too high since montis like high light. At least mine do anyway

After seeing the white get more spread I moved the clam to the sand bed which is odd because with a par meter it's only roughly 120 par yet the clam has been open big and happy
