I have a zoa dominated 25g lagoon tank 12" deep. Lit with a Kessil A360we. Intensity and color both max out at 50% during the day for 2 hrs. I don't think low light is to blame for the stretched out stalks on a few of my zoas. I have around 50 different zoas and there are only 4-5 that are doing this. I ramped the light intensity up to 90% and color to 75% over the course of a couple weeks. The only difference I noticed was more algae growth. I am doing 20% weekly water changes with Red Sea Coral Pro Salt.
