Well guys I'm from Australia so summer has just finished pool was uncovered and let run free close enough to zero chlorine.
Now I have ordered a floatron and a dosing pump to automatically dose chlorine.
So from what I have learnt
My pool is 900gal I can get my liquid pool chlorine for $1.10l or $4 a gal for u yanks its 15% (I think) I need approx 700ml per day.
I will shock the pool with about 10lb of chlorine in powder form and then use a flocklant to get stuff out from bottom.
I also have to walk pool with prawn scoop to get all leaves and other **** out.
