You need to get your pH up and add some TA quickly or you can damage your pool surfaces and equipment.
Use PoolMath (either the app or the link at the bottom of this page that says "Old PoolMath Webpage") to figure out how much to add, depending on your pool volume. You want your TA to be at least 50 and your pH to be in the low 7's.
You also need to add stabilizer and chlorine. If you're testing with a good kit, stabilizer will show as 0 for any value below 20-30. So I would only add about 20ppm of CYA and get that dissolving (put into an old sock or stocking and suspend in the pool in front of a return, a bit in front of the pool wall so it doesn't rest against it). For chlorine, start with getting about 5ppm of FC in the pool while you get the pH and TA in line. Once you've confirmed your pH and TA to be where they need to be, and the CYA is dissolving, you can start the
SLAM Process.
What's likely happening is that you're adding enough chlorine to fight the algae but not to completely eradicate it. So it multiplies and make more. You add more chlorine and kills more, and makes more dead algae for you to clear up, but doesn't get rid of it completely, so it just repeats. You need to get your pH and TA under control and then follow that
SLAM Process to clean it up completely.
