Do I have red bugs or AEF??

I am seeing the tips of my acro's look terrible. I am thinking red bugs. Please look at my pics and give your opinion? Thanks in advance!!

Looks more like alk burn to me can you post your Parameters.

My water has been good. Calcium 400. Kh is 7. Ph 8.2. Nitrates 5

I feel like every time someone ask what the parameters are they lie about the ph

What are your phosphates? Have you made any changes to the recently? Any parameter spikes in the past 2 months?

I use GFO in a reactor. I switch it out ever 4-6weeks. No crazy algae bloom or anything. But, I have not measured my phosphates recently. My alk has been running slightly low, but not too bad. ph has been over 8 consistently. It is only affecting Acro's. My pocilloporas, lepto's, monti's and LPS have been fine. It is starting at the Acro tips...which made me think red bugs. I had it in a different tank years ago, and the same thing happened.
