Hi all. My pool (12m x 6m rectangular - built by Desjoyaux France) is new this summer and I'm experiencing continuous problems with algae. The pool system is uniquely DesJoyaux design - the pump circulates the water back to a filtration bag which I am changing & cleaning every 2 days. I've got the PH level down to 7.0 ( I live in a calceous water area of France) and the chlorine level has been kept high. I've shocked the pool with 2kgs twice this summer and I am cleaning the bottom & sides every day with a robot which operates for nearly 4 hours each time. However, the problem continues. Can anyone advise me as to the next steps ?
