I found a response from Seachem that should answer your second question: http://www.myaquariumclub.com/ammonia-in-established-tank-will-not-drop-15026117.htmlYour right I was looking at the wrong line. My Highest level detected is Chlorine 2.02 ppm and Chlorine Dioxide 430 ppb.
From what I have read the chlorine Dioxide comes out just like Chlorine (aerating the water) but no idea how fast it will happen. I also would assume any chemicals that removed chlorine would remove it also but I can't find any info to support that.
Just for academic purposes, I contacted seachem with this question.
Does prime take care of chlorine dioxide and if so in what dose. My local water supply comes from nearby mountains and it is very soft water with a PH of 6.8, they dose chlorine dioxide into the water and I believe it is killing my beneficial bacteria even when I'm using prime.
This is their reply.
Thank you for the email and for using Prime. Prime will break the bond of any type of chlorine and/ or chloramine, leaving only non-toxic chloride atoms.
I hope this information helps. Let us know if you have further questions.

So it looks like you assumed correctly in that dechlorinators will also remove chlorine dioxide. 430ppb converts to .43ppm so you would want to dose for about 2.5ppm chlorine. Still half as much as you were using before![]()
