What would be considered a good alk range for SPS? At what level is the alk 'too high'?

I was reading an article in the smithsonian magazine the other day about reef bleaching and they said that water temperature was a main factor in why the reefs were dying and bleaching. The lighting wouldnt necessarily cause the bleaching, it would cause the corals to turn brown. From what I have read, you are running anywhere from 750 to 1000 watts of lighting which is not nearly enough to keep sps in your tank. To keep sps in your tank you need at least 7 watts per gallon of metal halide lighting. That would put you at a minimum of 1470w. Take the temp of the water, there is a reason why corals can mostly exist in tropical environments.
If the temp is too low I would suggest getting a heater and if the water is too hot get a chiller or a fan for your sump.

Your tank is very new, so be patience, I would start with small frags instead of whole colony. Your tank husbantry is fine, and your levels are good. The coraline are begining to take off is a good sign. make sure you have alot of random flow when you do SPS. The seios might not be enough.
some minor adjustment.
alk 11 might be a little high. I've found that when alk is at 7-8 and calcium at 420 my tank seem to have the best growth and color. When I was running alk @11 my tank seems to have more fatalities, now everything are thriving.
hope this help

I wonder still how foster and smith sell as many wild colonies and these guys get them to live???? I know most buy the colonies have established tanks....
what do most people do buy frags and watch them grow????I guess that would make sense
