Algae or pollen?

[obryan2579]

So I’m being a hypochondriac about my pool. My pool has a lip about 2 feet down all the way around. On one side in one corner I get a small buildup of either pollen or algae or something. Only in this one spot. It’s green and wipes away like dust, I did an OCLT last night and lost exactly 1ppm FC. Cc 0. Daily consumption of FC still averages around 4.5-5ppm. I have lots of pine that are dumping particulates. My CYA is 50. Im trying to convince myself. It to slam. Do you think that pollen is collecting in the same spot due to the current flow? I can’t imaging algae would only grow on this one little area. You may have to zoom in to see the problem stuff

Losing 1 ppm FC overnight is enough reason to SLAM. Your high daily consumption is also good evidence, depending on how much swimming is happening. I would SLAM it if it was mine.

Certainly no harm in SLAM'ing the pool for piece of mind.

Just under slam during the day for swimming, little over at night for fuzzies

Bushing and swimming will really help
