I have a 125 that has 4 x 96 PCs that I keep soft corals under. I recently bought a 6 x 39 T-5 fixture for a 40g breeder. I decided I wanted to movie a small xenia frag I have over to the 40g, and I put it at the bottom. It looks like the xenia is like wilting from going to a too strong of a light. how can I acclimate some of my softies from my 125 to my 40 light wise, and should this even have happened?

125g 384w or 3w per gallon.
40g 234w or 5.85w per gallon
Two things. You have 2x watt per gallon. If this tank is shallower then the larger tank the light is brighter at lower part. Water refracts and reflects light so further down less bright.

The 40g breeder is is 16'' deep if I remember + 2'' deep sand bed... the 125 is 18'' deep with a sand bed less than 1''. so big difference there

Xenia can take a blasting of light without wilting IME.
I would put my bet on water spec being different than what they desire.

i dont think its light either. i think its water parameters. xenia tend to do better in matured tank.

buy a bunch of clear plastic covers made for covering regular flourescent fixtures from home depot and stack them above your 40 after you have all the corals in there, then remove 1 every day or so to increase intensity....

Watts per gallon is an outdated rule of thumb. With different lighting like T-5 and Metal Halides, it doesnt work anymore. Only for freshwater, for salt we go on a PAR/Lumens rating.

a few months old maybe.
no copper or any other meds used except hypo...
amm- 0
nitrite - 0
nitrate- 5ppm
cal 520 ppm
We need an alkalinity reading as well, and calcium is quite high, Im going to bet alkalinity is a tid low.

It doesnt apply to fresh either. Only thing that matter is intensity (lumens) and wavelength.
