CC never 0

[Easto]

My last test results were:
CYA - 40
FC - 6
CC - 0.5
CH - 100
TA - 90
pH - 7.5

Every test I have done with my TF100 I have had a CC of 0.5. Anything under 1.0 is fine, but is there a reason that I would always have 0.5, and never 0?

That's completely common....my pool is the same.

Treat .5 as if it were zero....that's why we suggest .5 or less as the standard.

I didn't know if it was a situation were 0.5 is good, but 0 is optimal and preferred. I am using the BBB method and it is dummy proof so I thought maybe this was an issue I was having. It's good to know this is normal. Thanks
