Hi,
Pool: pebblecrete and SWG, +- 48000 liters
PH usually around 7.8 / 8 and chlorine around 5/7 with CYA around 30.
Have some very light staining mostly near return jets. Have tested with vitamin C tables and removes stain but larger areas so thinking I need to do the Ascorbic treatment.
Just concerned with taking the chlorine level to 0 and how low it can stay there before algae appears. Looked at a free bottle of algaecide i have but it is copper based which from reading would not be good to use. Is there a product suggestion from an Australian based members or is chlorine level of 0 ok for a few days? Do I have to take chlorine down to 0?
Last time shop measured copper in water they reported 0.2 (presume ppm) and within range of 0 - 0.3?
Also any Australian members have suggestions for the Ascorbic acid and sequestering agent?
Also found this product (Culator Metal Eliminator | Aussie Supplier | Lowest Price) which seems like its used/developed in USA?
Any help appreciated. Thanks
