Can this be used for dechlorinating tap water for aquariums?

I use this product for getting stains and yellow spots out of table linens.

Most minerals do not expire because they are natural elements, furthermore vitamins don't really expire they may lose some potency

Where in the bottle is the expiration date or manufacture date? I dont see it anywhere

I don't see a date. My last purchase was May, 2019 and it still seems to be working fine. I'm reading information from different data sources for an expiration of 12 to 18 months.

I don't think sodium Thiosulfate is good for the human body. In fact I actually think it's bad because all I use it for putting patina on metals. But I'm not an expert on what's a poison, or a chemist. But I wouldn't eat it or feed it to anyone I loved unless I did some serious research on what it does to the human body with an experienced chemist or an MD who's a poisons expert.
