I just added the 36" hybrid on my reefer 350. Ive been running 2 kessil A360WE's for a while and wasn't that happy wit the setup. Since putting this fixture up I'm extremely happy with how the tank looks but I'm not getting ant real increase in par according to my seneye sensor. I had been running my kessils about 12 inches apart 7 inches off the water line at 50% color and 80% intensity and getting 225 par 17 inches away from the light directly under the center. This is the highest point of my rock work. After adding the 4 t5 bulbs I'm getting about 250-260 par at the same spot... I was expecting to have to tune down my kessils a lot but I think I'm gonna leave them right where they are for now.. with the kessils off and just the 4 T5 bulbs on I'm getting about 45 par across the middle of the tank. Is this normal ? I've never run T-5's I went from MH to LED so I have no idea what to expect ?
