I need help, my gsp has not been open for about a week but I know it’s still alive because it has not lost it’s purple color. I moved it higher in the tank to a spot with more flow but it has not done anything so far. My zoanthids are covered in this green algae and don’t seem to be opening too well either. I tried to gently brush the algae off with a toothbrush. I was wondering if anyone had any advice for me. I do water changes about every week or so and there seems to be no water parameter issues. I was wondering if my LEDs might be too much for them, I have a 12 inch LED white strip and a blue strip. I was thinking about ordering a dimmer to make the white light less intense for them. What do you guys think?
