My Blue Table Acro Tips are Turning White
I know there is another thread on a similar subject, but my situation is a little different:

I recently received a nice small colony of blue table acro, and the tips initially turned white when I acclimated to my tank. the white doesn't seem to be traveling any further down yet (very tips have turned brown now), but I started 2 part dosing shortly after I received this. Here is a log that I have been keeping, and would like comments/suggestions.
Calcium jump was due to a miscalculation on total water volume, have not dosed Calcium since first dose. I have been trying to find guidelines on alk and Ca, and hard to find, so I am aiming for 450ppm Ca, and 10.0dKh on alk.

75gal, 30gal sump (60 gal total water volume), 4x54W T5HO's (2-blue plus, 2 Aquablue special) actinics=8hrs & daylight=10hrs, mag 9.5 w/SCWD and 4 outlets, 2 Koralia 4's.

Here is a short log of my parameters:

July 26th, 2009

Salinity: 1.024
Nitrites: 0
Nitrates: 0
Ammonia: 0
PO4: 0
Ca: 360ppm
Alk: 8.4dKh
Temp: 78.9
pH: 8.0
Started 2 part dosing today, added the following:
62ml Alkalinity solution to begin trying to achieve 10.0dKh
170ml of CaCl added, 1st of 3 doses of 170ml to achieve 450ppm Ca.
Will begin daily dosing once parameters are stable.

July 27th, 2009

temperature: 78.8
ammonia:0
pH: 8.0
nitrite: 0
salinity: 1.024
Nitrate: 0
Alkalinity: 8.4dKh
Magnesium: 1460
PO4: 0
Calcium: 464ppm

Calcium slightly higher than desired point, 100ppm jump after dosing last night. Need to re-calculate total water volume. Alkalinity shows same value, noticed that reagent is expired, need new test kit for alk.

August 1st, 2009

temperature:79
Ammonia: 0
pH: 8.1
nitrite: 0
salinity: 1.023
Nitrate: 0
Alkalinity: 8.0dKh
Magnesium: 1450
phosphate: 0
Calcium: 472
New test kit for Alk, reading lower than expected. ave not dosed in a few days, new alk test kit reads 8.0dKh, need to raise slowly to 10.0, Calcium still high and have not dosed in a few days. Added 40ml of alk solution.


August 2nd, 2009

temperature: 79
Ammonia: 0
pH: 8.0
nitrite: 0
salinity: 1.024
Nitrate: 0
Alkalinity: 9.0
Magnesium: 1460
phosphate: 0
Calcium: 464

Calcium coming down to desired level, alk coming up. Dosed 40ml of alk solution to try to achieve desired point.

What is your question? Calcium at that level will not adversely effect sps. Alklinity swings or changes in lighting may.
