I have been having problems over the last month keeping my fc at or around 5ppm.
I shocked the pool last week in respose to my similar post to this as some suggested I may be fighting an alge bloom.
I currently have my (oversized) SWG to 70% while running my pump ~8 hrs. a day and continue to lose FC.
Overnight FC Loss Test resulted in an FC loss of .5
Here is a set of numbers taken this morning:
FC 2 (Down from 2.5 last night)
Curious if there is anything else I can check BEFORE I call the manufacturer and make myself soud stupid.
