I have corals in the tank with comparable light: 90g tank, 24" deep, 110W (10,000K : actinics = 3:1) PC light by AHS.
What is growing and what level:
Bottom and the lower third: sun coral (light independent), white lemnalia, and surviving, but not growing well - Capnella (Kenya tree), Anthelia, GSP. Zone, directly under the middle of the lamp, does better, than the corner of the tank.
Middle ~6"/15cm of the tank:
green hairy mushroom, GSP, white xenia, capnella. Surviving, but not growing well - bright red mushroom.
Top third: everything is doing quite well, frogspawn, hammers, blasto merletti, monocolor thin-stemmed candycane, GSP, BSP, white xenia, white lemnalia, anthelia and capnella tried to grow out of control, yellow polyps, orange zoantids, bright
red mushrooms, blue algae ochtodes, even light-green scolymia and pink lobophyllia close to the top. Now acan echino is on the trial in the middle of the tank.
Growth is not so fast, as with twice more light (I'm keeping subdued light for a fish), worse of all are red mushrooms, but they like light.
