Allagash,
Your problem is not at all unique. It is the most common issue on the forum, always.
First off, if your posted test levels are correct, you have NO Free Chlorine in your pool. Free Chlorine is what kills the algae. You have none.
You DO have Combined Chlorine. That indicates your Free Chlorine has been used up killing algae.
As long as you've little or no Free Chlorine in the water, the algae is GROWING, faster and faster. The only way to get rid of it is to kill it faster than it grows. Here, that's currently called The Shock Process.
On June 25 you were told what to do. Right? To get the Free Chlorine level to 15, and hold it there, by continually adding chlorine. To check it by testing. We thought you understood.
Then you disappeared for nearly a week, and returned aggravated. Totally frustrated. And it's understandable.
You see, we have no idea what, if anything, you may have done during that time.
Did you follow The Shock Process in Pool School?
Have you read Pool School? It takes several readings to understand the information. That is the basis for everything discussed and recommended here. It's not magic. But it does require some learning. And some work.
The only solution for you, the Pool-Stored consumer is to take charge of your pool yourself, with acquired knowledge from Pool School, and this forum to guide you as you learn.
But first you must decide whether you wish to be responsible for your pool, or you want somebody else to be responsible.
The assistance you require is not beyond the board's abilities. In fact, it's a multiple-times-daily occurrence.
If you require assistance, please continue to provide current test results, and report back what you are doing/have done, and what is changing.
Read Pool School, with special attention to THE SHOCK PROCESS. Take notes or print it out for your use.
That's where you start. THE SHOCK PROCESS. Read it. Do it. Use Pool Calculator.
NOTE: . . .Shock is not a one-day bag of powder to toss into your pool, unless you're a store owner who wants to rip off customers. (That kind of product is to toss in after high bather load to give a little boost to your chlorine; no different than several ounces of bleach.)
We've all been exactly where you are. Now you are here, and we are here for you.
You're moving in the right direction!
