Clear, but no chlorine???

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.

[BigDave]

@CarlD: I have a cylinder I use for testing that has a 5ml line (I suspect you do too) from a different kit. The K2006 comparator starts at 10ml.
@mary jo: Perhaps you have another vessel that can measure 5ml. The dose cups from children's medicine comes to mind.

Not that I'm an expert, but... You can use the patented CarlD shot glass dilution method of chlorine testing to get a start this weekend. Mix 5 shot glasses of distilled water with one shot glass of pool water then test the mix for chlorine and multiply by 6. Not accurate enough to know when your done but good enough to start the shock process.

You intended those instructions for the weekend only (when she was out of 0871).

Also, I believe she bought the 16oz bottle so she should be good even with the 10ml sample.

If not, Mary Jo, I still have an extra 2oz bottle of 0871 if you need it. I am leaving for VA Saturday morning so you would need to let me know today.
