Hi and welcome! Can you tell us what kind of pool you have, what kind of filter you have and size of pump. Also, we need a current set of test results taken with a drops-based kit. We will also need to know exactly what all you have put in your pool meaning ingredients, not just product names or "shock."

Sounds like you are using an OTO kit. You really need a better kit. The one we recommend is the Taylor K-2006 or 2006C (same kit, larger bottle of some reagents). If you buy it through the Amazon link in my signature, the Pool Forum makes a little money on the sale which helps us keep this form online. Only buy if the seller is Amato Industries, however. Some other sellers are substituting the K-2005 which you do NOT want. If Amato isn't listed, wait a day or two and try again. They seem to restock pretty quickly when they sell out.

Repost with requested info and somebody here will try and help you.
