Quick Question about coloring and skirts

[naterd1976]

I recently received a frag of red zoa's from a local reefer. The strange thing is that my zoa's skirts seems to have gotten longer and less deep of a color than that their brethren in my friends tank. As a matter of fact all of my zoa's skirts seem to lengthen and loose a little of the deep color? My question is this: has anyone had this issue and what was the cause? I suspect lighting or maybe lack of nutrients.

Tank specs:

90 gal RR
0 ammonia
0 trites
0 trates
430 calcium
10.2 dkh alk
1300 mag

High flow, zoa's are in the lower half of tank. I skim 24/7 and feed every other day

6 bulb T5 rig
Icecap 660 and 430 ballast
color scheme
3 super actinic +
2 aquablue (11000k)
1 6000k daylight

Any feedback would be appreciated.

i tend to believe long skirts are enticed with high flow. as to the lightening, maybe one of the new actinic t5s from uv that are coming out, or you also might try feeding more often.
