sps quick question?

[fishpimp69]

Just was wondering why some of my sps's are brown and some are very bright and healthy looking. My water paraments are as follows:
ca: 390
ph: 8.1
Mag: 1060
nitrate: 0
ammo.: 0
phos: .01
KH: 11

I really don't get why half my corals are brown and the others aren't? Check out my bio for info on my tank and please feel free to give me any suggestions. I have tried lowering my photo time to mh on 6 hours and atinics on for 11 hours. Worked alittle but not the results i'm looking for.

anyone?

You could bump your Mg up to 1350 and your Ca up to at least 400. I would shoot for in between 400-450

Your cal and mag both are low

when bumping up mg how fast can i do this? Or how fast should i do this?

Bring them both up over a weeks time. Don't add more then what is recommeded on the reef chemistry calculator. Watch your pH when you bring them up as well.

Also, what about your pH and temp swings during the day? These should be kept as stable as possible.

How long have you had them?
Wild or tank-aquaculture?
Pics?

How stable has the tank been?
What bulbs are in?

IMO, get Mag up, drop Alk a bit ... and reply with more info, pics might be nice.
