Cyphastrea bleaching

[aidensav]

Could this be from too much light? Its around the same level as the favites in my tank.

Nitrates: 0
Phosphates: 1.0

phosphates are high, I would lower to 0.05 to 0.01, nitrates should be brought up a bit

 

[Baldyreef]

would light level would you say its in? low, moderate, high?

Probably low-moderate.

 

[Baldyreef]

Probably low-moderate.

great! then it is most likely the high phosphates and no nitrates

low and high light are subjective, some consider 150 par to be high light, in my tank thats low light, know what I mean. Better to give all the details if you can; type of lighting, what do you have for flow, what are the parameters? What you are showing us can be from anything, so more info is better. Full tank pictures are also very helpful

agreed. Tank is a little cloudy with a coral grow from AI on 66%. Flow is SLW-5 jecod with syncra 0.5 silent. Its weird that the exact spot a crab was sitting on for a day is bleached.

Rest of the params are
calcium: 400
alk: 10

Both have been stable
