too much light??

Hi Martym

Corals sometimes bleach under new light bulbs or new light configurations. I find that the colour of my monti caps is darker in lower light than high and right under the lights. You can try moving the bleached corals down out of the the direct light and then slowly move them back later or just reduce your photo period and bring it back over a few months. I would move the bleached corals leaving the photo period alone as all your other corals are doing fine.
