Thining Zoanthids after change from T5 to LED

[240gallons]

Was running 4 x 54 T5 fixture and had unbelievable Zoa growth. Moved to LEDs a couple years back and Zoas have receded BIG time! LPS are still doing great.

Any suggestions?

Definitely the reduction of light..you could buy two metal halides and run them for 4 or 5 hours during the day when you're not planning on admiring their color under led's...they'll come back.

These are near the surface where they get great lighting..
