I am new to this site and am very happy to have found it. We have had our pool for 5 years and never had any trouble. We had a local pool store with a great lady that never pushed all the specialty elixirs. She sold the basics and even suggested the BBB method when people were comfortable with it. Unfortunately she passed 1 1/2 years ago and it's not been the same since. So, 2 pool stores later I am feed up. The pool has never been the same and we've spent triple what we used to. I ordered the TF-100 today and am awaiting it's arrival. My water is clear right now, but I have some sort of algae/mold issue I will be posting about in the correct area. Looking forward to being self sufficient.
