What par level is best for burning banana stylo. I have other stylos that like around 150 par and the burning banana seems to be bleaching. Odd because every other coral in tank looks great and my levels are 3ppm nitrate .08 phosphate . Alk 8 ca 450 mg 1400 temp and ph stable no swings. Potassium was low at 360ppm slowly easing to 400. Any suggestions ?
