Question on how much chlorine is actually produced?

[PoolGate]

I know but it's been 2.5 days now. cc is always 0.

You are done when:​

• CC is 0.5 or lower
• AND you pass an Overnight Chlorine Loss Test
  This test is intended to determine if your pool has a contaminant such as algae that is consuming chlorine. The test is performed by testing FC in the evening after sunset and again in the morning before sunrise. The readings will be the same if there is nothing in your water consuming chlorine.
  Synonyms:
  OCLT

• AND pool water is crystal clear with no visible sign of algae (dead or alive) on floor and walls

Process can take a week or two. If it was low for a couple weeks it’s gonna take a couple weeks to correct. Just stay the course.

With clear water & an overnight loss algae is hiding somewhere.
Check & scrub all the usual suspects.
The absence of cc’s doesn’t mean there’s no organics even though the presence of elevated cc’s indicates a problem. That is why it is only one of the 3 end of slam criteria.
As mentioned above-
You are done when:

CC is 0.5 or lower;
You pass an Overnight Chlorine Loss Test
AND
the water is clear.
(Crystal Clear w/no algae dead or alive)

*Check & scrub every nook & cranny where algae may hide (light niches, steps, drain covers, ladder handrails, skimmer throats/weirs, etc.)
*Run slam level water through all water features & lines for at least a couple hours a day during the SLAM Process.
*Brush & or vac daily (this breaks up biofilms that algae uses to protect itself from chlorine)
*Backwash/clean filter when pressure rises 25%over clean pressure.
