Well that picture was taken with NO aquarium lighting on at all, just a camera flash... I personally only use VHO's as I am not into sps at all. I do have a few sps that do fine up top under the vhos...
I really don't like the 20K bulbs, they are way to blue IMO, you can make brown corals look blue even... 14K is a little better... But with halides I personally prefer the 10K with actinic.... Good thing there is lots of selections for all the different tastes out there...
Most blues I have seen dull out rather quickly under bright light... Not these though, I have a friend that has them under 400Watts of halide and they are blue as can be.... Actually I have noticed that the blue gets brigher and less of a dark blue when they are in the bright lights....
Also have some of these blues.. They are more of a blue in the middle that blends into a purple color towards the outside of the oral disc.. But very nice IMO....
Hopefully I will have my small frag of these blues with green frill tonight... (Hint hint JNS, get out the power fragger, I'll be over at 7)
Good thing the last couple blues are very fast growers, unfortunatly the waiting list is long, lol....
