I've been doing well for a while now & pool has been clear and blue. I thought of two questions that will help me understand more......

Should the CC ALWAYS be zero? If you get a little pink on the CC test even though FC ppm are 3-6, does that mean you have to do the whole "push the ppm up to 15 until the three indicators are met" thing again?

and

Now that it's cold & we are not swimming, do I still need to mainain the ph and other levels besides chlorine, or is that just for when we are swimming? We do not "close down" or cover the pool (we live in FL) - we just aren't swimming because it's to chilly.

Thanks!
