+1 on needing size of tank, specifically height. I have a 24/7 on 24/7mode on a 20long(~12" tall), its raised about 6 inches off the top and I still get algae in the top 2 inches of the tank without any additional co2. Hygro sunset basically tries to carpet.
I think it is important to note that the PAR values of the fugeray are not really representative of the 24/7. If I recall correctly, the planted+ 24/7 has a higher PAR value than the regular planted+ which is also higher than the fugeray. It is my understanding that, on max, the 24/7 is similar to the RAY 2. Look into Mattinmd's 24/7 guide on this forum for more info.
