The quick answer is that your pH at that levels isn't too bad. It isn't optimum, but it is not likely to be causing any problems either.
The longer answer is to read the articles mentioned and think long/hard about how challenging it really is to move your pH to a higher level without causing serious harm to anything while you do it. It can be done, but trying to adjust pH is not something that is generally recommended.
