Chalice lighting question low? or Mod?

[BuvRahl]

I'm growing acros, montis, favias, acans, aussie lords, blastos, etc without a problem. The par range I'm seeing for Chalice is 80-250... that's a pretty huge spread. I've got two chalice frags that are showing some tissue loss that have been either on a sandbed (1 day) or frag holder at about 20% height from the bottom.

Any experts out there that can give me some advice? 120 gallon tank, with two ap700's, dual gyre 250's, refugium.

ph 8.1-8.2
alk 8.5-9.5
salinity 1.026
temp 78-78.5
ca 440
mg 1400

Any help appreciated.

I have a Miami hurricane that’s around 3 years old, it was in the center of tank about midway up on a rock ledge for a year or more in mod-high light and never grew that much or looked that great until I moved it to the side of my tank in lower lighting and it exploded in growth and has developed beautiful colors.. guessing maybe 100-150 par
