I just thought of another reason to buy USP. Pretty obvious reason. You'll need to buy MORE of the inferior grade than the USP.

USP will be ~50% water. Lower grades could get way higher. In fact I would say they'd let it absorb water on purpose to make it weigh more.

I just calculated what I actually need for my tank, 375kg. For my previous batch (of China crap) I bought 450kg and had to add all of it to get the S.G right.


Obviously it differs from place to place, but I'm actually spending less on USP grade than I did on the shitty China stuff.

Hi Kane, what contaminants have you had before?



I'm kinda worried about mine right now. The water is clear and everything, but I've been reading some from China are contaminated with heavy metals, and I found out mine is from there.


Did you get yours tested, and if so, how?


Thanks.

Comment
Thanks Kane. Yeah I was more concerned about things like mercury and cadmium, since I'm not gonna be drinking it, most other metals probably wouldn't be a big deal.



Definitely looking in to getting it tested just to make sure, It'll be cheaper than ordering new salt half way across the world. I got quoted $50 for heavy metals tests but they have to dilute the water first (coz of all the salt), meaning they would only detect it if it's 10x higher than what is considered safe, so not really useful. Waiting to hear back from other places now.

We only purchase USP grade so ours haven't had any contamination issues except for once with the hot water heater draining and dumping all the sediment. This was more of a discoloration issues as minerals oxidized.



It was our associate who found a significant amount of sand which messed up their plumbing system. At face value, I wouldn't be so concerned about heavy metals as the most common is iron and lead toxicity, of which neither can pass through the skin easily. Furthermore, the are "heavy" metals, which makes them just that.... heavy with specific gravities of 3-4 so they will sink in the solution. If you are finding you just can't shake the concern, you can always have it lab tested but this may be cost prohibitive (a couple hundred dollars).



Here is a good article that should set your mind at ease

Generally USP grade is recommended to insure no contaminants. We have seen, in the past, issues where non-usp grade salt was added to a float pod and contaminants required emptying and refilling at a cost in time and money. With that said, however, Giles is a very reputable company. Jim Hill, the CEO is a great ally to our industry. All Epsom Salt manufactured by Giles is USP grade, it is simply the packaging process that differentiates them. I think you found a good product at a good price.
