My pool builder provides their own pool person for 30 days after plaster. I was curious how they are able to maintain my pool with only 1 visit each week and no real water testing.
before he came, my pool was pH 7.4, FC 4 - he did quick dipstick test claiming my pH was 7.8 and FC was 0.5 - dumped in bunch of acid and chlorine.
After he left: pH 6.8! FC 10!
Since they are here only once a week, they obviously have to front load the chemicals so that it there's still some chlorine left and the pH isn't too alkaline by the time they return the following week..
I can't wait to get rid of them and go BBB
