Hi.

I have a little combined chlorine confusion with the taylor fas dpd test.

The issue im having is this.

Example 14 drops for FC but then get an immediate pink reading as soon as i start adding the CC drops. Or 15 drops for FC and no colour change when adding all 5 CC drops.

Which is correct?
