The pool wasn’t getting much debris so I didn’t vaccume for 2 weeks. So when I did it today I noticed for the first time green spots on floor. They wouldn’t come up without a scrub. Than when I was swimming I noticed spots here and their I missed and was able to get it off with a foot rub. Was this stuff algea ? Was my fc too low to cause this ? My water is clear , so no issues their . I’ve never experienced this before. Also it’s my first summer ever owning a pool so I don’t know if this is commit or not. Thanks for any knowledge you guys want to drop on me

Algae is always a chemistry issue, unlike brushing and vacuuming which are mechanical issues.

If you're seeing green I'd either go full fledged SLAM process now, or at least run an OCLT for confirmation.
Overnight Chlorine Loss Test

How about some test results??

That 3ppm of FC is kinda low..... too easy for it to drop below your minimum level for comfort. I'd suggest taking it up to about 5ppm so if you lose 2ppm a day to sun you'll still be over minimum.

Good idea thank you. You know what is puzzling me. If that was algea on bottom of pool. And I scrubbed it all up I’m surprised I don’t have and cc.
