Hi Folks... I'm a 2nd year pool owner but 1st year pool boy as I fired the pool service.
I'm currently testing with a ColorQ7 and I've used non-chlorine (MPS) "shock" thus far. After reading the site, I've learned this isn't really going to impact CC and that my DPD3 testing is in error. Adding more MPS is not the right action, which is what I had been doing to reduce what looked like high CCs.
I now have the Taylor DEOX R-0867 reagent but I don't know if I'm using it correctly with the ColorQ. This is the process I've used and results..
1. ColorQ testing (no reagent)
Results in CC of 0.20
2. ColorQ with DEOX
a. blank meter with same sample
b. Standard FCL test with DPD1 and DPD2 (five drops each)
c. Add five drops R-0867
d. Add five drops DPD3
e. invert once, tap to remove bubbles (no stir or shaking)
f. Read TCL
Results in CC of 0.00
I think I can conclude that I actually have CC= 0.00 and MPS = 0.20. Is this correct?
BTW... I now have some education (thanks pool school) and awareness that these results show my CYA and FC are out of sync. I welcome any general input.
thank you in advance!
