Thanks! I only take the canopy off to replace bulbs, so now I can clean bulbs, reflectors, all the salt creep, clean the overflow out and so on. Good Saturday project! I also read this morning that fans shouldn't be blowing over the middles of the T5s which evidently decreases the life of the bulb; they should be directed over the end of the bulb with the logo according to Grim Reefer, so I will be moving those as well.
