FAS-DPD I forget.....

[AimeeH]

What is the best way to test at very high chlorine levels? In order to reduce reagents used? I forget. I don't see it in the extended test kit instructions.

I didn't think it included any dilution.....a search brought me to that. I need to order reagents but also need to slam.

Isn't there a way to test (less accurate) CL levels in the higher double digits with less reagents?

Are you thinking of 10 ml instead of 25 ml and each drop being .5 instead of .2 FC?

Some people have tried 5 ml with each drop being 1 FC, but I think I read that accuracy really suffers when it's that concentrated. I've never tried it.
