A low K RATED BULB will cause coraline to bleach. like some 10K bulbs will cause it. it could be the clear water from the dosing and the bulbs too.

Changes in water clarity can certainly cause bleaching, most noticeable after the sudden use of carbon. Anything that suddenly clears the water can increase light penetration, which in turn can cause corals to bleach.
