I guess every pool is a bit of a different situation.
last test
FC 5.5
CC= 0
ph = 7.6
CYA 50
CH =450
Salt 3200
I have found that when I run my salt pool at TA =90...I have a higher acid demand than TA = 110. At 90, which is the acceptable high limit...my pH bounces up to 8.0 or higher (purple color) often/weekly and I am using more acid. Learning on TFP that TA is a pH buffer...I tried an experiment bumping the TA up to 110....and it seems to keep the pH more stable. Since I am a Test Engineer, I am always finding something to run a test on...LOL.
Also, after two seasons of SLAM at early spring opening....with CYA at 20-30.....I bump my CYA up to 50 and the IC40 seems to be just fine keeping the FC around 5.5-7.0, 40%, running 9 hours per day (3x 3 hours per time zone). The recommended CYA level for SWG Pool is 70-80. The first year I ran CYA at 50 was because I ran out of Stabilizer and never had time to go get more (or really forgot)....and realized at CYA=50 things looked really good for the whole season.
I have an IC40 SWG running at 40-60%. After SLAM this year with cooler than normal spring temps all the way up to June 10....the FC level stayed above 10 for longer than I expected. I actually had to set the IC40 to 0% for a few days to get the FC to drop. FC is now down to normal levels... the last test around 5.5. The pool looks great. My Nautilus CC Plus and skimming daily keep everything in order.
Just thought I'd report this anomaly....every pool is a tad bit different.
