Hi I have never had problems with my pool before, but I ignored it and now it is not happy with me!
I have a few spots, almost look like dirt on the pool. Wont brush off. Went in and tested pool, said no FC. PH was high. I added acid twice to lower ph and put in shook treatment one bag. It is better after a day but still have areas with the algae on them.
They are recommending a yellow out, algaecide, clear aid product, phosphree product, and then a de filter change, when I did a change two weeks ago.
Would love advice please...thanks
