Received my Taylor test kit. The powder for the chlorine test did not arrive with the measuring "dipper". Can anyone tell me approx volume of the two dippers one uses to conduct the FAS DPD test? Looked on the video to be 1/4 to 1/2 a teaspoon. Thanks.

Ph below 6.8 yesterday; added four pounds borax. Up to about 7 today. Will add more borax today.
CYA: 50 (no more di or tri chlor)
FC: between 5 and 10 on the test strip and appears to hold well during day.
TA: about 40 (only test strip test ).

I want to shock tonight; I estimate I need to bring FC to 20 ppm, which would be approx. 4.1 gallons of bleach (6%)

Does this sound right?

Thank you

You only need enough powder to change color -- it doesn't even have to be a dipper full.

BUT, the dipper quantity is MUCH less than 1/8 teaspoon. If you have some dry popsticks, and can whittle that down to about 1/4" wide, and then dip out enough to cover the tip of the stick, that should be more than enough.

However, you should call an request a new bottle. That dipper is a fairly critical item.

Regarding bleach dose: with a 30K gallon pool, your PF is 4, so each gallon of 6% bleach will add about 2 ppm. 10 gallons will add 20 ppm.
