So putting the kessils inside the canopy, just a few inches higher dropped par on the clams from 500 plus to 350 or so at sand bed.
Tried 33 degree reflectors and that got 425 or so at sand bed.
Decided to lower canopy 4 inches about and use 33 degree reflectors. That got me 500 to 650 par on the clams depending on location. T5's and reefbrites take care of the rest of the tank at 175 to 300 par (at bottom of tank) on the edges depending which edge.
Anyway, kessil 360's do not have much punch and fade quickly on par after say 10 inches into the water. Every inch after that loses substantial par. I would say the 360's have really no better par than 160's, as to punch through water, just better spread.
You can add punch, however, with 55 or 33 degree refectora. Thats super cool in my book. I get purposely varied par in the tank catered to each critter. Clams are toasting at over 600 on the sand bed. Just 8 or so inches away, torchs hang at 180 to 220.
The kessil 360 in all blue have a slighter whiter look than 160s at all blue, but it looks nicer IMO.
Figured id post this all in case someone is playing around with kessils too and may not have a par meter. My tank is 16 inches high, so use that for rough heights of lights and such.
