KH of 10.2 is okay. Someone correct me if I am wrong here, but KH between 8 and 11 is great

pH of 7.7 is low. As I said in my post on your other thread, get more O2 into the tank room. More O2 and less CO2 will bring up pH.
You might also look at the biological processes that are going on in your tank. Over feeding will cause more of the alkalinity to be utilized. So will having dirty filters and not doing frequent, regular water changes. What kind of filtration (if any) do you use in this tank? What is your tank maintenance schedule? What specific things do you do during tank maintenance and how often do you do maintenance?
