Waterbear,
ORP at 700 is approximately FC of 6.
At night as the sun sets ORP might get to 725, but only if I run the pool into the night say 10 pm to 11pm if my children are having a party and I set it higher say at 775 will it ever reach 750.
The main issue I believe is that we live up at about a 1000 ft and trade winds averaging 16 to 24 mph blow very fine dirt into the pool. So 800 will never happen unless I run it 24/7 and we do not have the money for that. Trade Winds are an issue for most pools in Hawaii, I love the trade winds it keeps us cool on hot days but they do blow around a lot of dirt.
I would really like to get one of those low pressure pumps that one can run 24/7 that uses only a little electrical current but sadly they are only manufactured for 2" lines.
So FC of 6 it is. The pool is brushed daily so there is no algae of any kind present at this time that we are aware of.
Thank you for your help.
