Advice: Unhappy tank..
Background: 90g tanks, 130lb LR, 150lb live sand, Remora Pro, 33g sump,
I have 2 pink skunks in my tank, a small bubble tip and a Yellow Colt. Problem: My yellow colt has been white for the past 3 weeks, it goes through it's normal opening up during the day and it closes at night.. lately it looks a little more droopy than usual. It began fragging when I bought it and I think it may have completely fragged now. Nearly all of my tests that I have checked look good. My amonia, nitrate, nitrite and calcium are all in check (0,0,0, 400). Specific gravity fluctuates between .024~.025 (depending on my water changes etc.. I just checked last night and my pH is off the charts, much higher than the 8.3 is right now.. i think my readings go to 8.6 so I'm guessing my pH might be closer to 8.9 or 9.0 right now. THe big question I have is whether the pH is the cause for my yellow colt turning white.. and what's the best way to lower my pH down to the 8.3 range.. at this point my plan is to get some baking soda and slowly lower my pH over the next week. Any suggestions on how to get my yellow colt back to it's proper condition & pH levels back on track will be greatly appreciated.

Re: Advice: Unhappy tank..
Before doing anything, recalibrate your pH meter to make sure it's correct. Also, what is your current dKH? If your pH meter is right and you have a low pH, then adding baking soda so KH is between 8 and 11 dKH would be useful in your situation.

lighting etc
I have 260w power compact, water temp is around 80~81F, and it gets indirect water flow.. it's in a slightly sheltered cove on the front of my tank where the power heads won't directly push water... the colt is about 1/2 way down my live rock, so it shouldn't be getting to much or to little light..
confused.. :S

Re: lighting etc
While 80-81 isn't really hot, I keep my tanks at around 78F in the event ambient room temps raise tank temps. Also, I make sure there is lots of surface agitation for good gas exchange allowing for maximum O2 in the water. SG is 1.025 to 1.026 which is maintained by adding RO/DI water daily to make up for evaporation because of the high surface agitation.

Unhappy tank..
In my experience a high pH can cause bleaching. If you are adding buffers you maybe overdosing. There are some other suggestions in this article that may be of some help.

KH
I checked my KH last night and it's roughly in the 120 range.
Will apologize I have very little background in chem etc.. so my numbers are usually based straight off the readings I get from my tests. The package gave me two interpretations for the 120, in one area it said anything between 105-125 is good for salt tanks, and then in another area it said if it's over 90 than it's to high.
