Hey Tom, how are you doing? Would you do me a favor and address this comment by Jon. Just curious:
Bruce thinks ppms are vitally important but I think he's got it wrong
what is important is how much you need to do the job and it may be more or less in terms of ppms.
When we activate we get more ClO2 because that is what is doing the job
You get a little from unactivated sodium chlorite but it isnt as effective
