Is my fc usage normal or is there something else going on?

This morning with oto drops it said I had at least 5 fc. I put enough chlorine to add 4 more fc. I checked it this afternoon and its at 3 fc. It is 94 degrees and 106 with heat index.
I added enough to bump 3 more we are about to swim.
Last yr it consumed about 3 -4 a day
I forgot to add that the evening before I added enough to add 4 fc after we got out of pool

What is your CYA level?
It may be too low causing you to lose FC to the sunlight?

30 last time I checked. We've had lots of rain though

If you're not fighting the start of an algae outbreak, low CYA could be to blame for higher FC loss. You might want to bump it up to 10 and do an OCLT to reassure yourself?

And I meant bump chlorine up to 10 in that last post. But also check your CYA
