Hi have a 15m x5 m in ground pool with desjoyaux bag filter system, just bought house and water green, I balanced ph alkaline ect level and shocked with peroxide on advice of pool shop filter left on 24/7. Algae gone after changing bags every couple of hours. Now left with clean but cloudy water. Ph levels all ok but chlorine level showing zero. Using clearing tablets that are not showing signs of working.
shop said not to add chlorine for 3 weeks after shock with peroxide other than tablets.
what can I do to clear water and raise chlorine levels.
