Which spectrum bulbs are good for SPS?

[jkhudson]

Which bulb is better for SPS's? 10,000k, 14,000k, or 20,000k? Actually, while I'm at it, what's best for what? TIA

The best spectrum for growth and health would be the 10k. The 14k and 20 bulbs are for viewing pleasure. If your are only concerned with growth and health, the best would actually be 6500k, but the water would look like a child peed in it lol. The 6500k is real yellow, closest to natural sunlight.

the lower the kelvin rating, the better the growth....but yellow color.

I personally get great growth with 20,000 XM bulbs.

Coralvue reeflux 10k's are the whitest 10k's you could get, besides the aqualines. They look good without actinics, even XM's 10k looks yellow compared to them. They also make a 12k or 14k in the Reeflux. The standard coralvue 10k's are really really blue. Almost as blue as my Radium bulbs

EBHD, the coralvue is 10K spectrum is almost identical to a 20k. I think Sanjay Joshi showed the curves for them a while back. I used to have them before i moved to the 20K xm.

I am assuming you were refering to the standard coralvue 10k's. I used to run them along side an xm 20k and there was almost no difference in color. I think you were the one who started me on the coralvues in the first place. Didnt you used to run them on your 240

by the way, here is the spec plots for both the xm and the coralvues

and here is the link to Sanjays website

Yep, thats right.

I had good growth under them, but I still prefer the XM 20K

The brightest light i saw was the Hamilton 10Ks. They were incredible

The spectrum is the same for all bulbs. Their intensity on the other hand can be quite different. It's usually the intensity that damages the livestock.
