Can't get PH up can someone help

[buddah001]

I have a newly set-up 65 gal tank. Put in 80 lbs of live rock 40 lbs of live sand. Have a etss sump with a etss reef devil skimmer. The tank has been up for 10 days now. Ammonia is low -.25 nitrite is -.25 my alkalinty is at 6.0 mEq/L but I can't get my ph over 8.0 I have used Kent Marine Aquarium ph buffer with no help, I have used Kent Marine Superbuffer-dKH with no help I bought some Kent Marine Expert series Pro Buffer dKH but have not used yet. Any suggestions. PH sould be about 8.4 correct?

Since there's still ammonia showing, I wouldn't worry about the pH. The decay process tends to produce acids that lower pH. Stop dosing the pH buffers, since they are just high-pH alkalinity supplements. I migh.t do some water changes to lower the alkalinity.

8.0 for pH is fine, especially in a new tank.
