I got a Chaeto ball for my refugium about two weeks ago and it has been struggling lately. Included is a picture of it and the fuge as well as the light I am using. It is a cheap hygger light from Amazon that is 8w, 778 lm, and 6500k. What can I do to bring the Chaeto back? I was running the light on full power for 12 hours per night but I just decreased it to 10 hours per night and lowered the brightness a bit. Is this too little? I was concerned about burning it at the initial strength. All help is appreciated!
