OK I need some help

OK temp in constant, no optics, they are, 3 watts ran just over two, the corals are low to medium. They vary.

 

Did you adjust intensity recently? How often do you feed your fish? Possible your Foxface and/or Tangs are nibbling? What corals specifically are doing bad, and which look OK? Any chance of coral warfare? Do you run carbon?

 

They get fed everyday. No adjustment

 

How much do you feed them though, what and quantity?

 

The newest thing you did was add the reactor , Don't know if that could have a negative effect???

 

No it has been going on before the lights and reactors.
