I have read both the view that a pool should be shocked following various situations (heavy rain/bather load, etc.) as well as weekly, and the view that shocking is not necessary unless testing indicates it is. I would rather not shock "just because" and only do it when necessary.

I am using a Walmart drop test and so far have not noticed any difference btw. my FC and CC readings. Is this test kit accurate enough - the FC is supposed to be read immediately and then wait 2 min. to read the CC. It's always the same. I'm supposed to look for ~.3 difference in values right? Is this OK (identical readings) and means I don't need to shock?

I always add chlorine at night and in the morning the levels seem to be the same. This is also an indication I don't need to shock, right?

Am I watching for everything I need to so far?

I will definitely get a better test kit next year, this one kind of drives me nuts, I want something more precise, this is like "ballparking it" - then again, what do I want for $12.99 I guess....

Thanks very much!!
