I would think if that stuff settling is only happening in the pool within the hour it may be algae. If it was related to the area (i.e. pollen or dirt) you would have accumulations around the pool, on your car, patio furniture, etc. You've mentioned the water was clear with a slight "tint", so go ahead and try the OCLT if you still can. Let's see if you lose any more than 1 ppm of FC between now and in the morning. Of the choices available, algae is the easiest to treat because that's a straight-forward (SLAM) process. If it's not, and that yellow/green tint is from metals in your water like from previous algaecides or something from the pool store, that's a much different matter. So let's see how your test results look in the morning.
