I have same setup. 40 breeder with current IC pro 24” dual light setup. First tank (started March 2020) and added first anemone in January 2021.
My (limited) experience is that these lights aren’t quite strong enough for anemones. My nem moved to very top of tank and has reduced to about half of original size and lost a lot of color since being added. I will have to check settings per
@Spare time recommendations. Have about 8hrs of daylight settings, plus ramp-up ramp-down. Tried direct feeding but still seemed to be struggling.
Regardless I was worried about nem and light seemed like major issue. So I just added “cheap” 36” 2 bulb T5 light. Went with ATI blue+ and coral+ bulbs. This was about 2 weeks ago. Slowly ramping up T5 light time, only about 1.5 hours per day right now. Nem is puffing up more during T5 time, starting to show small bubbles again and regaining some color. Think I’m on the right track with added T5 but time will tell.
Color and size (2-2.5”) when Nem first added to tank.
Took a clean up crew tug-of-war joy ride before settling in.
Don’t have a great current picture. But nem is right near top right behind the torch. Went directly to highest point in tank within first week, which made me believe it wanted more light. Again only half size of original with faded color.
Current lights have been great for softies and euphylia growth. Hammer split and GSP on back wall is about 4 months growth from base rock. But still didn’t seem like enough light for the nem.
Hope this helps.
