NANFA-L-- pH and fin erosion/rot

I have a few tanks set up with grass pike. In one tank a small individual (3.5") appears extremely healthy, eats well etc. But, just recently I noticed the edge of all fins begining to turn white with some appearing ragged. I have read that extremes in pH may lead to fin rot...or stress that can cause bacterial fin rot. The pH of my tank is on the higher side of normal for freshwater-in-8.23. Is this higher than normal pH enough to cause stress that could lead to fin rot??? What are other causes if not and will salt help with the cure?
