Is this FC too high for a saltwater pool?

[smallpooldad]

Have a Pool Pilot Total Digital SC60 set to power level 2, pH to 7.5, ORP is set to 700; but mostly stays at 650 between 11am to 3pm when the pump runs. GPM is 55. Pool size is 10,000 gals (32 x 9.5). Taylor readings except Borate and temp.

Love this unit, I wish I had gotten one 12 years ago but then again had no money.

FC 8
pH 7.5
Alk 100
Borate 50
Calcium 280
CyA 40
Salt 3000
Temp 88

Pool is crystal clear.

Location: Honolulu, Hawaii

Pool is covered with a clear bubble as trade winds (16 mph to 26 mph
) reduce the temperature considerably.

Eyes sting a little after 20 minutes. Only remove cover when I swim 7pm to 8pm. There seems to be no negative affects to plaster or stainless.

Is this FC too high for a saltwater pool? And is ORP or FC a better gauge of how well sanitized a pool is? Am I keeping the pool cover on too long every day; can it therefore have a negative effect?
