OMG. it's always something!
Test the FC today and it was 7!
I guess the cool weather and a 50 CYA is helping our chlorine situation???
It's all over the map
9/13 FC 2/cal 425/ta 100/CYA 60/pH 7.8
9/15 2 FC/calc 350/ta 80/pH 7.5
9/17 FC 8.5/pH 7.6-ish/CYA 50
9/18 FC 5.5/ pH7.5, 6
9/19 FC 5.0
9/21 FC 2 - bleach added and SWG turned on <it had been not working but got it working>
9/23 1/4 bottle of CYA and and FC 8.5 and CYA 55
9/24 FC 8.5/Ph 7.7/CYA 55
9/25 FC 4.5 and added 12 oz of acid/CALC 375/TA 100/CYA 50/pH 7.8
9/26 FC 4.5
9/28 FC 7/cya 50 pH is 7.8 again
I know that chlorine eats acid. Hubby wants to wait and get the FC down before adding more acid.
Thoughts???? I have a notebook. I don't test everything every day. I only have enough solution to test the CYA one more time. We have ordered more already. it hasn't arrived. Turned the SWG down to 20% - this is just crazy!
