Not sure about AL bulbs but if you buy two supplementals I would go with either two ATI blue + or one Blue+/One ATI actinic. I prefer the look of two BLue plus and it has the 420 built in to it but I'm currently running one Blue + and one actinic for dusk dawn to see if my corals color up better. Running two blue + the tank is much brighter.
