So I've been testing Chlorine now using the FAS/DPD test. We started off with FC at 9 with the salt cell running at 60%. Kicked to 50 and then 40% with no change in FC. Using 10ml sample so each reagent drop equates to 0.5.
I then dropped the salt cell to 25% and saw the FC decline to 8.5. Excited since that's been the first discernible change.
So a couple of questions.
Does the amount of powder in the scoop matter greatly? I'm guessing not as they would provide a more exact way to measure because that scoop is small and you could easily get 2x the amount of powder you'd need if you just dip and pick. But if so, this could account for things.
So if this is a discernible change, I wonder how low I could/should go on salt cell. I know I could go to 0 physically.
The only othe thing that would affect the production would be the flow rate of water through the cell and the time that the pump is on, right?
I'm not "worried" about having too much chlorine because botching with grow then and I'm good with that...lol. But there no reason to burn out the salt cell before its end of life...
Other readings of interest:
ph 7.6. Was 8 but added muriatic to drop it)
BTW, confirmed FC range by using the other test with the color comparator and was in the 5-10 range. Also CC was 0 there as well.
