Watch polyp deployment. Soft corals and many LPS

it's harder to tell as they can go all at once. On of the challenges with SPS
. But again, watch for healthy polyp deployment and for any signs of loss of color. If it continues to look fine, crank the light up a tiny bit and watch for a few days. Visually, the LED
will look dimmer, but actually producing more usable light for your coral. Why it's so easy to accidentally bleach corals with LED
, it just doesn't look that bright.
I find taking IPhone pictures from a marked location of each coral once a week gives me a real feel for what changes help or hinder growth. Happens too slow for you to gauge it visually.
