Yesterday I got the filter hooked up and the pump running--all is well so far. This morning I took the first water test, using the TF-100 kit. Here are my results (11,500 gallon pool):
If I'm right, I need to get the CYA up to a decent level (30-50), using some stabilizer. Then I can get the FC up to a proper level using good old bleach. I don't quite understand why the TC reading doesn't match a FC + CC sum.
In any case, I'm off to find stabilizer, and will check back here later in the day.
all best wishes,
