The test results I posted were from the local pool store. I do have the DPD test kit but as I said I want to the local store for more accurate readings. This morning pool is looking better but still cloudy. My from my DPD test kit this morning were FC - 3 and TC -5 so I think I still have more shocking to do...do you agree? I've been using 4 lbs and have done that 3 times over the past 48 hours. Do I need to increase amount of CHL I'm shocking with? Thanks for the note on the liquid CHL. I was always wondering why people used it. Why have I heard this group take about Clorox? That isn't the same as Liq CHL is it?
