Fine Tuning a Salt Water Pool

[BigTallGuy]

I installed a SWCG about a month ago, and have gained an incredible amount of knowledge and information on this Forum. I realize that These are FAQ's but here goes. Approx 11,500 gallon AG pool.

First my readings from this afternoon:

FC 5.0
TC 5.0
CYA 50
Salt 3300
TA 120
pH 7.4

I am currently running the system 5.0 hours per day at 100% output. The FC reading above was taken at 4:00 p.m. approximately 15 hours after the pump shut off, and 4 hours before it is scheduled to kick back on. I have read the "Best Guess" thread regarding the CYA to FC ratio and would like to know if these levels apply to salt Water pools as well as Traditional Chlorine pools.

I am having to add Muriatic acid to keep the pH level down and have read a lot of info on his forum regarding this. I seem to be adding less amounts less frequently as my CYA level rises. I did nurse the CYA up slowly, and I have cut my "on" time from 8 hours to 6 hours to 5 hours.

It would seem likely to me that I can reduce my amount of "on" time or reduce the output percentage still further. With respect to the rising pH level, which would be better, the shorter actual "on" time or the lower percentage?

I would appreciate any and all comments or feed back.
