Pollen green?

Being your neighbor (Alabama), I'm experiencing the same thing in my pool with a similar wooded setting. One way to tell if its pollen or not is to get a fairly constant wind direction for a day or so and the pollen will "pile" as it settles on the liner on the downwind side. It is notorious for settling down the sides of my pool. I have to run my pool cleaner and keep the water "stirred" so that the pollen will remain suspended in the water long enough to be filtered out by the sand filter. The DE trick helps as well.

Just a thought for you. My pool is under a large live oak canopy and when I first moved in the water was never completly crystal clear. I too thought it was pollen because I had repeatedly shocked it in addition to running the SWC at a high level. I was finally convinced here to run the Cl levels up high and keep them there for a few days until it reslolved, all the while vaccuming daily. That did the trick and I've been a believer since. Now if ever there is a water clarity problem, that has worked for me. It's a cheap, easy fix. Also probabaly you aren't swimming much yet, so it's a good time to tie up the water for a few days and get it ready for the season.
