OK I felt like an expert last year - managed to keep my pool clear all summer.
This year I am already struggling - perhaps because we are having so much sun!!! Not that I am complaining.
I am shocking at the moment but my cya is low. For the first time I need to buy cyanuric acid and I guess I need it in the liquid form so it works fast.
Can any one suggest good products and approx price please - dont want to get ripped off at the local pool stores.
