My pool been TroubleFree for so long. Have not superchlorinate for so long.
Yesterday my pool got its new awning/shade and the amount of dirt I have to content with is a fun factor for testing.
The old frames were steel. Lots of water enter the frames hollow. Lots of dust stuck and turn to mud.
Lots of corroded steel debris.
I know my water been stable due to my learnning at BBB University and I am only needing to remove particles and not organic problem,
here is the result..........

[attachment=0:vap3nmyo]3 - Rust from old steel frame - only shown 20% of it.JPG[/attachment:vap3nmyo]
I was betting I will need 8 x 4.7 hours = 38 hours to get 8x turnover and get pool clean again.
