I just received my TF100 test kit and here are my readings:
The pool calculator did not indicate that I needed to do anything. But it shows my TA should be 100-120, mine is 400 and yet it did not tell me to do anything. Just wanted you expertise thoughts on this.
I am so glad I found this site. I have had horrible experiences in the past two years with the pool store. I am hoping to have a nice clear pool this year since I have found this site.
