We are returning to the UK for 3 months from the high heat of a Thai hot season. Last time we did this trip we returned to a large Algae problem that took a long time to fix. Does anyone have some tips on how to maintain the water quality while we are way. I cover the pool with a black thin cover that keeps the water temperature cool but should I add extra chlorine to shock level before we leave?
Any advice will be gratefully received and thanks again to all who have helped me in the past
