Lights
1. 2 48” 50/50 reef bright
2. 2 48” blue reef bright
3. 5 360x kessil
4. 1 kessil 500x above my SPS rock
360x on with ramping cycle
My problem is they are hung higher than recommended resulting in lower par than initial intended.
I have done par meter twice, but not since adding the 500x. (So par does not include 500x)
Sand is 80 (near edges) to 110 (center)
top of water runs 80 (edges) -280 (center)
1/2 way down 80-120
im surprised that close to the sand runs a similar par than 1/2 way up on the sides.
Depth does not decrease par substantially in my tank.
