So I’ve been having a problem with my fuge. It would not grow with a Luxbird fuge light from Amazon. I upgraded to a Kessil H80 set to 100% intensity and 50% in color. I run it from 8pm to 8am (12 hours). At the same time, I added a powerhead to have it tumble. All I’ve noticed is the parts of the Chaeto break off and get on the powerhead. No growth. In fact, it now looks smaller since pieces have broken off of it. May nitrates are super high, 80ppm, and phosphates are at 0.25ppm. I keep seeing many say to dose ChaetoGro. Should I do this? Are my light settings correct? What am I doing wrong?
