Ahh the Holy Grail.
Ahh the Holy Grail.
Eye popping coloration the Holy Grail for SPS freaks like us . . . I sympathize my brutha :bum:
Certainly no lack of advice out there, and for sure lots of great tanks here on RC to chose from for mimicry all using slightly different lights, dosing, feeding, etc, BUT I can't help wanting to help you with your quest so here's my 2 cents (and that's all its probably worth, but what the heck

)
1) small amount of Rowaphos and GAC in a reactor
2) 10k bulb with actinic supplementation
3) shorter MH photo period like 6 to 8 hours
4) try B-Ionic it seems to me to be like crack cocaine for SPS
5) raise your rockwork higher; bring the purple and pink SPS closer to the surface
6) try some type of variable flow in the tank
7) bring the temp up above 76
8) bring the alk down to 7 to 9 dKh
9) bring the Mg down to 1350 to 1450 ppm
10) find corals that are widely successful and colorful like the
Stylophora or the
Tort
There's a lot on that list, and its largely personal preference, plus I know its hard to sort through all the input, but like I said just trying to help
Best of luck, and be sure to keep us posted on whatever you try as well as what you observe!
