strips suck,since your using strips,i wouldnt be surprised if it were nitrate or nitrite causing it

well, I have neon green colony polyps, a purple passion tree coral, and a spotted mushroom coral ( my tank is kind of beginner) and they're all doing fine

Move the coral higher because maybe it's not receiving enough light. How often do you do water changes? If they are frequent, then you don't need to add any supplements.
