Clear, but no chlorine???

Agreed.

Only 3ppm loss last night. Good progress!

yesterday evening's test results:
tested @ 10:15pm FC=34 CC=1.0

this morning tested@ 7:00am FC=33 CC=1.0

getting better…

i had a question about testing with diluted water: I am currently testing using 5:1 ratio (distilled/pool). Is this OK or would a smaller ratio ( i.e. 3:1) give me more accurate results?

Hey, hey! Only 1ppm loss! Getting better!

As for diluting, they're your reagents and history has shown you aren't afraid to use them to excess If you want more accuracy and don't mind using more reagent, I would suggest just doing it for the overnight testing.

Good job! You have learned a ton!

I'm sorry if this should be obvious, but, for which tests are you using the dilution method?

[mary jo]

I've been using dilution testing for FC/CC and CYA.

[BigDave]

You are diluting the sample for the FAS-DPD test? If so, please don't dilute it more than 1:1. Yes, it will take alot of R-0871 - you might want to order a 2oz bottle. You are getting close to the end and I'm concerned that a 5:1 dilution might be skewing your measurments.

[CarlD]

Why would you use dilution for the FAS-DPD test (head scratch) ?

Merely fill to the 5ml line (or halfway to the 10ml line if you don't have a 5ml line) and count 1 drop = 1ppm of FC.
