Hi all! Just a quick question I couldn’t find directly searching as pertains to me.
CYA just under 70
Currently in SLAM process

Slam level is supposed to be 28.
Will the FC maintain that level overnight if I am finished with the process?
Last night I lost 4ppm.

Thanks in advance!
 
More drops needed means more chance for human error, but a 4ppm loss is likely still organics/alage.
 
Ok thanks.
Maybe one last question so I am clear.
Aside from human error, FC wont dissipate overnight at those high levels on its own unless its still working to get rid of something correct?

I’d rather not lower the CYA.
