Dummie LED Problem

[Leelalie]

Where to begin, all was well in my aquaruim till.........(before lights classic LED hybrid de 2x 7.7 w 390 lm)
i added a new light...
eheim marine hybrid power led+ 1156 lm 14.8 w 445 nm
i thought my tank was going down. Coralline went fluo and then white and 2 shrimps died in a week. my corals is closed during the day ect...

did a 50% water change and all my water specs good, but my corals stay closed during the day
Now my question is and i have been reading alot, is it the lights setting that is influencing my tank?

Shrimp dying is not because of the lights. What are your water parameters ? How old is the tank ?

well your nitrates and phosphates are zero.Thats why your corals are dying.

then why do they open early morning and late afternoon while the lightning is less intense
