You can do an overnight chlorine loss test (OCLT) to see of its really algae or just dirt. The pool looks clear otherwise.Gotcha! Thanks.
Here is my water-it’s cloudy here, so may not have a good picture. It’s actually crystal clear. Can see a tiny spot of algae back after my husband vacuumed to waste about 2 1/2 hrs ago. (The 1st photo was before vacuuming.)
I think I am gonna add another dose of chlorine to bring my fc up to 12 & go from there. And leave off the Bacquacil!
Thanks for your help!!

Perform the Overnight FC Loss Test (OCLT)
The Overnight Chlorine Loss Test tells if the SLAM is finished or if you need to start a SLAM. This article says how to do the OCLT.

Some people try to perform a SLAM with calhypo or dichlor and so I was asking about what type of chlorone you were using. Some folks with extended SLAM process problem added a lot of cal hypo that makes the water cloudy, but you dont have that problem.
