Hello Salty1:
A little tough love...... You are not using your pool while you wait for a guy who only comes once per week (when he is not on vacation) to try to "fix" the "mess" he created. Kind of crazy, right?
No one, and I mean NO ONE, will care about your pool more than you will. You are more than halfway to being out of this mess since you have a SWG and found TFP. Here is the hitch to get you the rest of the way home - it will involve a little work, a little knowledge and a very little bit (relative to the pool guy) of money for a test kit.
Sure, it all seems daunting now. But there are a lot of good folks here who have helped literally thousands of people in much worse situations than yours. It is a one step at a time process. We can kick it all off by you picking up a good test kit, and running the numbers - should take about 20 minutes or so. Then just post the numbers here and someone will give you the next step and you are off to the races.
I hope you reconsider letting your pool guy handle the situation.
