Hi Janet - you're right, typo! Both FC and TC were at 20 this morning. I'll test again tonight but we've had a cloudy cool(er) day so I don't expect for it to have come down too far yet. I've let it settle since brushing it this morning and decided against the vac. The water is continuing to clear and I can't see anything down there that I should vac today. Not much stirred up with the brushing. I did backwash and rinse though and it looked pretty ugly even though the pressure hadn't risen. Fortunately it looked black for the first time in the viewer and not green so we must be killing the algae in the filter too.

I went out to search for DE and couldn't find any in town. Two managers at Wal-Mart didn't even know what it was. I didn't expect much - we live in a one horse town I sometimes refer to as "Lower Crapovia" and there are very few pool owners here. Wal-Mart also doesn't carry MA so I'm still going to have to return to the aloof pool dude at some point.

Thanks again for everything. I love this place!!
