i appreciate the suggestion, but its not sounding right to me. i don't see anything on any other surfaces and i think i do recognize this as algae.Hello! I’m no expert and have owned a pool for only a year now. Just tossing out an idea as I can sense it’s been a frustrating experience for you.
Reading through your thread, it seems you’ve maintained some really high chlorine levels for some time. I also notice that your location is listed as New Jersey.
I’ve got a friend in NJ who said that ragweed pollen is really bad there now. It started at the end of August, which roughly tracks with your statement that you’ve been seeing the yellow streaks on your pool floor for about a month.
Given that it doesn’t seem to be responding to chlorine, and apparently isn’t clinging to the walls of the pool, is there a chance this is ragweed pollen in your pool? Do you see it on other surfaces (like your car) or perhaps floating on the pool surface at all?
I don’t have enough experience to tell you how to test that theory, but I’m sure others here do. Just wanted to share that thought since I had just talked to my friend about the pollen problem in your area.
