Hey Everyone,

I’m new here and just had a quick question for anyone who might know.

I’ve read a lot of misinformation about the “bromine ban” here in Canada.

At first so many people were saying bromine was banned altogether, which after delving into the forums and the health canada legislation I found out is not true at all.

Apparently only bromine in conjunction with electrolysis, ozonation, uv generators/systems were banned and that the chemical bromine in every form as it relates to being used in pools/spas was not affected at all.

The misinformation runs so deep here in canada that almost every pool/spa store here in my city says they don’t even sell sodium bromide powder anymore to build a bromine bank as it’s illegal (which it’s not at all) you can still find it, you just have to find someone at a mom and pop shop who actually knows what they are talking about. I mean they even sell it on amazon canada lol. Anyways the health canada stipulations also state that using MPS with bromine was also banned.

Then months later I found a post on this forum with some guy saying that the MPS inclusion was only originally and then health canada did a review to appeals and after the review they recanted including the MPS along with bromine in the restriction.

I thought that was interesting (as I want to know if I can still use my leftover MPS in my bromine hot tub safely) so I went back to the health canada website to dig further. Upon rereading the whole original ban, then information on the review process and then the completed decision after the review was completed. I didn’t really see any section where they claimed that MPS is now allowed to be used again with bromine or that the original restriction was lifted.

This is where my confusion lies. Was MPS originally banned in conjunction with bromine period for a hot tub or was it only banned in conjunction with bromine ONLY WHEN using it in one of the aforementioned systems (electrolysis, ozonation, uv) with bromine?

If someone could clear this up for me it would be much appreciated. I usually stick to plain ole sodium hypochlorite to shock my bromine tub as it doesn’t impact TDS and PH however every now and then I like to use MPS to shock so I can verify that my bromine bank is still in tact.

Thanks in advance for any information.
 
Since you are asking for clarification as to the interpretation of a current law/rule....best would be to contact the appropriate department in Health Canada. Unlikely that anyone here can give a definitive answer as to what the current rules allow/don't allow. All we can do is give opinions on what it might or might not be.
 
Welcome to TFP.

Old news. It has been discussed here since 2020.

Only Health Canada can give you their position on it.

Right but that’s why I specified “safe” I don’t care what the law is, I just want to make sure that if I have a bromine tub and I use MPS to shock it I’m not releasing gases or toxins that are poisonous or harmful to me or family.

I don't know alot about bromine generators, which are just salt cells using sodium bromide instead of sodium chloride (salt). As I understand it, the gas generated can be dangerous. But then, the same is true to some extent for chlorine too. Maybe @JoyfulNoise knows more on the relative risks, but that was the crux of the situation as I understood it (vaguely, being in the US where everything is toxic 😉).
Ozone is an oxidizer, like mps, and in theory will convert bromide into bromine, though I can't say from personal experience how effective it is (I don't use bromine). I don't know if it gasses off any byproducts in either case, but it's possible.
UV will burn off chloramines, but I don't know the mechanism. I've read it might be producing H2O2 (hydrogen peroxide, an oxidizer) within the water just as it produces ozone (O3) in air, in which case it is oxidizing just like the rest.
Frankly, I'm surprised they let you use chlorine to do it either. Another bureaucratic mystery we'll need the all-knowing ChiaHead to unravel.😉
I have to add that chlorine sanitation byproducts are also not good for you. How much worse bromine is I'm unsure of, but in general no chemically maintained body of water is "safe" in the strictest sense of the word. It's a relative question, and "safer" would be a more accurate term. Chlorine is definitely safer than people soup, but not completely harmless.

I don't think any un-chemically body of water is safe either.

A chemically body of water is safer than untreated water.
 
We are essentially walking bags of sentient goo - any strong 'sanitizer' is at some point going to be 'toxic', it's just a matter of degree...

The trick is to use something that will kill off the unwanted nasties quicker than they will kill off us...
