The algae issue will be directly related to the height of the light off the substrate. I believe a 60 p is 12" deep and 24" wide. A 24" Ray2 is kicking out 74 PAR at that depth, you better be injecting Co2 unless you want an algae farm.
A FugeRay light of the same size is 45 PAR at that depth, Co2 would still be a good idea but you could get away with Excel/glut dosing.
With either light you could raise it higher (hang it instead of mounted on the tank) or use window screening to cut down the light. If I were going the screening route I would take the end cap off the Finnex light and slide the screen inside the plexi splash shield.
(Sorry Lowe - had to add something involving taking it apart
PS: From what I understand the HC and bonsai are going to require real Co2 injection to grow well, never tried myself.
