I have a t8 shoplight resting on my aquatium. It has a t12 6500k daylight bulb in it. (Purchased wrong one, gonna use this one for now). What effect is the wrong bulb having or is it alright? I planned to get a t8 6500k daylight but is this enough to keep my hairgrass alive and carpet? If not is there anything i could use in my t8 shoplight? Thanks
