Hi, Sam, and welcome to the Pool Forum.

No more clarifier or algaecide. Sometimes those makes things worse.

Please list the ingredients in the granules and in the shock and swim. Also, look at the label on the tabs and see if it lists copper.

Is this a newly filled pool this year?

Come back with answers to these questions. Also, go to our sister website www.poolsolutions.com. On the left hand side of the page, click on "guides" and read the guide about lowering alk. Does your pool have a return jet eyeball that you can turn upwards to create as much splashing as possible to aerate the pH upwards?

Do yourself a favor and order the Taylor K-2006 or 2006C kit we recommend. It will make everything much easier. (Link in my signature below.)
