Intex Sand Filter, still having an issue with pollen

The typical reason that filter pressure rises like that is algae.

Do a Overnight Chlorine Loss Test. Raise your FC as it was below minimum the test you posted.
Over night test was 7ppm last night and 7ppm this morning... Doesn’t point to an algae issue, correct?
So, I think we are going to replace the sand and restart the filter and see if I just messed up the filter setup.
