why is my pH so high

[chandigz]

I thought I had a pH problem years ago then I stopped testing. Now I have no problem. I'd worry more about keeping your calcium and alk in check. Your tank will buffer at what it wants to and trying to mess with it will only cause a rollercoaster effect. It's better to be stable whether a little high or low. PH will also fluctuate depending on the time of day and the type of livestock. I wouldn't worry to much.
