Although we are being a lot more patient this time, we have bought some Anti Algues Concentre. The instructions for curing algae say to put 2.5 litres in for every 100 cubic metres - this seems OK but it also says to add 100 tablets (comprimes?) of Chor Choc. This seems an enormous amount as we normally put in 30. Has anyone tried this and does it have any adverse effect on the pool. We are complete novices and are concerned that the water quality will suffer.
Thanks in advance for help/advice.
