I feel like I should disagree with you on this. I had a dual t5ho light over my 20g high tank for quite some time and grew softies perfectly well. I had great luck with mushrooms, zoanthids, pulsing xenia, leathers, kenya tree, and a trumpet coral.
The growth however did improve greatly when I added a 120w led
over my tank.
