Hi and welcome to the Pool Forum! I'm sorry you are struggling to get this clear. Hopefully we can help get you swimming soon.

My first question is .... what is your source of fill water? Actually, instead of me asking a bunch of questions, let me just ask you to fill in your pool's information in our pool chart.
Pool Chart Entry Form
Pool Chart Results
Also, please list all products you have used in your pool. Is your filter pressure rising? How often are you backwashing?

We'll start with this much and then go from there after we get some additional info from you.

By the way, thank you very much for the subscription! We appreciate the financial support because it helps keep our forum alive!
