I have an inground pool which we have just acquired with the new house.
The chlorine I measured yesterday (the pool has been opened some 3 weeks ago and I used the old kit, now I bought a new one and the reading should be correct) is a bit above 5ppm. Close to it but a shade darrker. That is about 6ppm I think.
I have an automatic inline chlorinator, a Pentair model 320.
There were some stabilized (found the bucket) 3" tabs inside since the ladt year, I added more (as I read somwhere on this forum you just put as many as you can there and set the dial, and then experiment with the level).
Now when I read 6ppm yesterday morning I set the dial to 1.5ppm (was at 3-3/4). This morning - no change. I just shut it off to see if tomorrow it'll drop.
Oh, and TC=FC, so it is not the bound chlorine.
So. what gives? Why is it high? Is the stabilizer at fault?
And, speaking of the latter, how do I avoid overstabilizing if I use those 3" tabs that I think are all stabilized?
I had an above GND before, ran it as copper-ion so have no tons of experience with chlorine and stabilizer.
