Bleach instead of Chlorine tab for daily/weekly maintenance

Are there any instructions on how to test with 10ml.

I am assuming:
10 ml of water
1 dipper DPD powder (correct???)
R 871 - drop wise - # of drops x 0.5 = FC
R 003 - Still 5 drops (???)
R 871 - drop wise - # of drops x 0.5 = CC

Is that correct?

But save your reagents and don't test at 25ml, test at 10ml. Each drop is .5 and that's accurate enough.

Yep. You got it!
