Overnight, in a covered pool with 90 degree water, how much FC loss should one experience? Assume the pool is "clean" (no algae, etc) and chemistry is otherwise ideal?
I have been slamming my pool every night for two weeks now. Every night, I take FC to 10ppm (my CYA is ~25). The next morning, FCF is ~5ppm.Every pool is different, do an Overnight Chlorine Loss Test to see what your pool is losing... When it comes down to it unless something is growing you should loose very little or no chlorine overnight... My pool when covered with a solar panel goes down to using about 1 FC in 24 hours "or so"

The filter runs 24/7. The water is crystal clear and there is no visible algae or sliminess on the walls.
FC 5 (this was 10 last night when I shocked it)
PH 7.6
TA 90
CYA ~25 (this was >40 a few weeks ago)
Temperature 88 degrees

The pool has an auto cover. It is completely dark all day. How is algae growing?Please READ the SLAM Process
Follow it STEP by STEP with no shortcuts.
The M in SLAM means MAINTAIN.
You must maintain your SLAM FC level of 12. Every time you test and your FC is below 12 you MUST raise it to 12 or above. The more often you test and maintain the faster the process will go.
What you were doing was killing algae early in the night and then letting it grow back during the day. You will never win the battle that way.

No, no other chemicals are going into the pool.You can have algae brewing in clear water. You just have not gotten a full green algae bloom yet. But it is lurking there just waiting for your FC level to drop and it will be off to the races.
If you have FC loss at night, and in a covered pool, it is only from one reason - algae. Unless you have been tossing in pool store potions or algaecides that contain chemicals like ammonia that consume chlorine.
What about bacteria? Since I was experiencing rapid CYA loss, this article (poolsolutions.com...) led me to believe it was an issue of CYA-eating bacteria.
