I'm considering ordering a few dozen pounds of fish intended for human consumption. Yes I eat fish too. I've searched the prime website and I can't get any information, does anyone know if I could safely use Prime to dechlorinate water for fish intended for human consumption?
Is Prime safe for humans?

oh god how did this get here i am n
Just did a little bit of research, but this should not be taken as actionable medical or scientific advice.
The active component of Prime is hydrosulfite salts. Since this product is intended for use on live animals, one can only assume it would be one of the safer salts with lower toxicity -- otherwise it would harm or kill your fish. For the most part, the toxic/deadly dose is very high on these chemicals and you'd probably end up with gastrointestinal upset and nausea before you could consume a lethal dose.
In addition, these products react and degrade quickly in water (they react with chlorine/chloramine) and the resulting products are less toxic/dangerous than the salts themselves.
Couple this with the fact that you're using such a minute amount of Prime -- so long as you're following the directions -- and the fact that the fish aren't actively ingesting it, and I personally wouldn't worry about any ill effects or health consequences.
That being said, as far as I can tell, Prime isn't labelled for use in food production, so I wouldn't go around selling the fish for food purposes, but for personal use, I'm guessing it's all okay.

^ Basically this.
That label is generally there for one of two reasons; A) it actually is dangerous or B) the label was cheaper then the study/test. Either way it'd probably be better to find something without a disclaimer written on the side.
Set up a rainwater tank? I have something like 2 30,000 litre tanks and only have Prime for emergancies. Even a small rainwater tank will be good for this use.
Reason is that any medicine that is approved for food animals needs to go though a MUCH more stringent testing procedure and runs into a whole boat load of different regulations.
So it's simpler to stick that label on the side and avoid all the red tape.
I would suggest it's 99.99% safe, but Seachem will not tell you that, for legal reasons.
You should be able to get a MSDS that lists the active ingredients and research those if you want to be more certain. Also if you intend to sell the fish for human consumption, then YOU run into that same red tape

No, it's definitely not safe. The byproducts of neutralizing chlorine and chloramine are much more toxic than chloramine or chloramine themselves, and can also cause birth defects. It may seem illogical but chlorine and chloramine don't kill fish by being toxic but by inhibiting oxygen uptake from the water. It would take far greater doses than 4 parts per million for chlorine to exhibit any toxic effect, and most tap water has that chlorine in it so again obviously that's not how it works. That's why I never use that crap.
