Lighting question.

[LostMind]

Tank parameters?

amm, trites and trates for both tanks are 0,0,0.
ph in mine is lower, 7.9 his is 8.1 (he has more hair alage)
calcium is 440 in my tank, 390 in his
alk is 13.5 in mine, 11.4 in his
salinity is at 1.026 for both
temp around 81 for me, 79 for him.

In terms of flow, I have roughly double the flow he has, but most of my flow comes from my pumps and get pushed thru my sqwd for wave action, he has 4 powerheads dropped in his tank.

My lighting is using 250w 10,000k Ushio bulbs. I beleive his are also 10,000k ushio bulbs, just 400w.

I am wondering... polyps are for feeding, right? So... if the coral is receiving a higher intensity light, it's food requirements will be met more readily via photosynthesis, right? So, in a lower light area, the polyps might be out more in search of more food?
