Hello pool forumers! my name is Mike! I'm new to this forum and would like to say hello to everyone!

I'm a new pool owner here and need a little help.

My pool is about 20,000 gallons
And I'm finally making some positive impact lol

Ph is 7.6
Chlorine is 3.0
Alkalinity is 130

I know 130 is a little high, and I would like to drop it some. Hopefully to 100....
I've been trying and so far so luck...

Any tips or help you guys could recommend?

P.s. my pool water is also cloudy... It looks like a sky blue type. I can see the bottom in the shallow but not the deep.

Thanks guys!!!
