I have been keep reefs a long time...and never been so confused as I am with LED lighting and it's effect on my LPS corals. Most of my SPS do fine. My biggest problems are chalice corals, brain corals, Euphyllia and caulastrea.
These are the readings given by the website of the Dsuny leds .
My tank is only a 90gal...20in deep. I have 4 T-5's-55watt each in the back. My 2-led panels are up front. I am assuming from the picture...my par might be higher at 100% because I have the same 2 units up front and my tank is more shallow.
I used to run them at 100%...and found brains to bleach, chalice, euphillia and caulastrea to recede suddenly and steadily.
So, I dimmed the unit. Running the blues at 50%(12hrs). Whites at 20%(4hrs). Still having trouble with receding on those corals.
Decided tonight....run the blues at 40%(12hrs), whites at 20% (lowered whites from 4hrs to 3hrs daily)
I am really at a loss. Water is fine. Most other species are great and growing. I have my brains and chalices in shaded areas now. Any advice is appreciated!!Never had these problems with Halides and T-5's!!
My question...Are they collecting more brains and chalices from deeper waters these days?? I read some people are keeping chalices at a par of 70-110!!
My tank...LEDS are mounted on the top of the canopy.
This is a link to the lights I have...2 panel manual dimmable unit.
