I went ahead and scrubbed it all up. Here is what I noticed characteristically about whatever it is -
- It's "dusty". Scrubbing it provides a dusty result.
- If you barely scrub it, you can actually see it settle back to the bottom (that doesn't sound like algae)
- It tends to be where the most shade is (characteristic of mustard, but could just be coincidental. More on that in a second)
- It is more yellow in color than most algaes that I'm familiar with, although it does have a green tint to it - almost like pollen.
- It is slimy, but not in the sense that it stays where it is when you touch it. It clouds away.
I'm not sure if it was in this thread or not that I've mentioned that I do live in the middle of the woods. There are many trees around, two of which almost hang directly over the pool. This is the shaded area - but the shaded area where the trees are also means that whatever this is could also be something out of the trees. I assume that it could be pollen, but I would think that most pollenation would have already occurred, especially with the early warming of this year. Of course, I'm not a botanist so some trees may very well release pollen all year long. I have no idea.
Anyway, now the pool looks great. The water has a slight cloud to it. I turned the pump on high for now to see if I can't clear some of that up. I'll see how fast it comes back. The photos that I posted earlier was about three days without scrubbing. I have not vacuumed in a while either. If this turns out to be some sort of dirt or other debris, I may have to go with an auto vacuum system.
