Calcium Hardness increasing (just curious)

We had a monsoon that flooded our pool, so it took a couple days to get it back in order. I have been taking daily readings and noted that CH test increases every day.
here are the last three tests
Taylor k-2005 with K1515
CL 12 8.5 5.4 (I have my SWCG off lowering CL as I superchlored it right after the monsoon)
PH 7.4 7.4 7.4
ALK 90 90 80 (played with jets to aerate (sp?) pool)
CH 200 225 250
CYA 80 NT NT
SALT 3000 3000 3000
I know that CH should be between 200-400 for plaster. Just wondering what would make it creep up, i have not added any water since the monsoon, before the monsoon CH was 290.

I'm not sure why your CH is creeping up. Maybe Ben will have an idea or maybe it is just a testing issue.

I just wanted to comment on one other thing. Don't use your SWCG to superchlorinate. That just shortens the cell life. Any time you need to shock, just use bleach and save the wear and tear on your cell.

Thanks for the info, I haven't really done the bleach thing, haven't read up on it enough yet. I know there is a lot of information regarding the bleach on this site.
