Looks like algae but passed OCLT

Ok thank you. I added my pool info to my signature I thought. Maybe I’m doing it wrong?

I have been testing with a kit from this site, TF 100.

I can’t remember my salt level right now but the pool guy yesterday said it was ‘good’.

I’ll get back to you on this.

Thank you!
 
For your signature, include all of your equipment, including model number, and that you’re using the TF100. That way whenever you have questions, folks can quickly figure out your pool situation and provide better answers. You can look at my signature as an example. Report back after you’ve added some liquid chlorine and we can figure out what’s going on.
