Welcome to the forum :handwave:

The best advice we can offer at this point is get a quality test kit, one of THESE recommended kits and read through Pool School defeating algae. Test Strips aren't accurate enough and don't cover all needed tests and we generally don't trust pool store testing. We stress taking control of the pool with self testing and the use of a few basic chemicals, no quick fix magic chemicals like shocks, algicides or flocculants.

It is possible to have clear water with algae in it. When you added the shock it likely killed a bunch of the algae and what you are seeing now as cloudy water is dead algae. Just because you killed a bunch of it you probably did not kill it all that is where the test kit comes in to play finding out your true FC CC and CYA levels once you know that you can go through a process we call SLAM and clear the algae bloom for good.

TFP is a different method from adding shock and using mineral systems and for the most part requires you do decide on the method that is right for you.

WOW! I can't imagine how much all that stuff cost?! We avoid most pool store chemicals as they're overpriced for what they are. For example- Alkalinity Up is just baking soda with a bigger price tag. Really! In fact, if you buy the big bags of Arm and Hammer baking soda from Sam's Club or Costco they even show a big pool on the front as one use.

We believe in doing out own testing with a far superior kit rather than rely on "Guess Strips" or often incorrect pool store testing.

If you believe those test results, your FC is terribly low right now. So between adding liquid chlorine (aka bleach) and some good filtering, I'd do that first and then re-assess with testing. The cloudy water could just be all those odd and assorted chemicals....or an algae outbreak.

Don't add any more granular shock products as they add either calcium (which vinyl pools don't need) or yet more CYA to your pool which you don't need either. The higher your CYA level the higher your FC needs to be.

If this is the start of an algae outbreak you're going to need to SLAM the pool-->

Holler back with any new questions

Oh yeah- I'm assuming you're in Manheim PA not Manheim Germany..... please add your state/region location to your profile on the left. It really helps us to know your climate and such.....
