Cloudy water with all tests in range?

[Fire]

Hoping someone can give me some direction on what to do next. My pool has slowly become cloudy over the past few days. I can still see the bottom of the deep end, but it's not as clear as it was say a week ago. All my test results are within acceptable range and my CC is either 0.5 or 0. I just added 1L of liquid chlorine to bring my level closer to 9ppm as I remember the pool being clear when it was that high. It's been a steady 6.5-7.5ppm via the SWCG before I added the liquid chlorine this morning.
Do I need to perform a OCLT when my CC is less than 0.5? What else may be causing my water to start becoming cloudy?
I've been running my 2speed pump on low for 12h a day for the last week (9am-9pm).
Sorry for the long post.

F,

Cloudy is almost always a sign of algae... Our recommended operating levels are designed to keep algae from starting, but if you already had algae, they will not kill it.. Bringing your FC up to SLAM level will..

You can do an OCLT if you want, but if the pool is cloudy, the best thing to do is a SLAM.. SLAM Process

If you do a SLAM early, it should not take long.

Thanks,
