Colin, did you read the quote in my initial post? Specifically this part:
Uniquely, Bioactive Tapsafe also adds a culture of bacteria and enzymes that consume any excess biological waste in the aquarium and boosts filter performance.
There's a sticky on water conditioners;

Sodium thiosulfate is fine for chlorine, or smaller water changes with chloramine, but not so fine on large water changes where the tap water is disinfected with chloramine, or where higher residuals of chloramine are used by the local municipality. For chloramine treated tap water I would highly recommend Seachem Safe. Read the sticky, it will make more sense.
Yes...I read it, and appreciated your kind feedback.
Thanks for the sticky, I'll have a look
