CC higher than FC

[beaverplt]

in the morning before work and at night trying for 12 hrs apart. It seems I'm adding shock more often at night than in the morning. Maybe due to sunshine? I haven't tested tonight yet, but it'll be interesting to see what 3 inches of rain did to the numbers.

Update. Just tested FC, CC, and PH. PH stayed at 7.2, CC stayed at .5, but FC went from 20 down to 13.5 in the 24 hrs. (I didn't test this morning with the storms.

Yup. That's UV that causes the difference. Maybe you can sneak in one more test and add as soon as you get home from work?

Got some DE into the pool this afternoon. Went exactly as described. Pressure went up one lb with the 1/3 cup. As an aside, it seems odd that the smallest amount I could buy is ten pounds, yet I only needed 1/3 cup. I'm thinking I'm set for a while. One other note, don't use your wife's nice measuring cups. They're not harmed, but you might be.

[FormerBromineUser]

Hahaha! Yup, better get your own measuring cups!

My dedicated pool maintenance supplies include a 2Q and a 1C plastic measuring cup, a toothbrush, a pot scrubber, a scotch sponge with delicate scouring pad, a plastic turkey baster, a roll of paper towels, a plastic long-handled spoon, and 2 buckets: one small, one large.

You can include the box of DE in your will. It may last longer than you will! Cheap, though, and worth it.

Lol!

I bought 2 huge boxes of DE that my children's children will cherish. Hah! BTW, what's the turkey baster for?

[FormerBromineUser]

Hahahaha! I use the turkey baster to shoot chlorine-rich water into my light niche on occasion. I don't take the housing all the way out; I just unscrew it enough that I can get the stream from the baster into the niche.
