Bleaching Rock and need chlorine test strips - FREE or Total?

Reefrock · 09/21/2020, 01:06 PM

Hello

I am in the process of bleaching some old Dry Rock that was given to me. I am going to order some Chlorine test strips to validate the chlorine is gone (adding De-Chlor). I see there are two types...Free Chlorine and Total Chlorine. Which one should I order?

Any help is much appreciated!

I've always used the nose test myself.
