Hi, I have a fiberglass pool and had to replace a lot of the water with well water this year (drained a lot to get to the light). So these numbers are mostly a victory
CH (pool store said they were low but I forget)
this morning FC = 2
TC well above 5 - that instant bright pink
Q1. is OK to add still more chlorine even though there is still a lot of "total chlorine" in there? will only free chlorine do bad things to piping?
q2. next step after I get the pool clear from shocking is to add stabilizer? and then calcium?
