I probably said that wrong, the tablets are actually in the pump, the are in a tube beside the pump. On that there's an adjustment which I usually keep around 2-3 which is about 50%. I've actually lowered it before to try to make the water cloudy and it seems like nothing I do will make the water in this pool cloudy. My pool builder said as long as the water is crystal clear don't worry about anything because the ozonator is doing its job. I have a hard time believing that and that it could really be this simple to maintain a pool so I am constantly worrying about when I'll wake up to a green pond in my back yard. :-)

I turned the adjustment by the tablets up to 5 (the max) yesterday just to see if the FC will come up or not. I'll take a sample today and post my results. But as I am interpreting your last reply maybe I should just stop stressing and enjoy the pool?

If I needed to raise the CYA at some point what is best used to do that?
