Since Dow is such a major supplier of this stuff what are the chances that even the suppliers of the "real" aquarium brands are using the same higher bromide stuff in their products?

probably real high, seeing as all of this happened last year sometime and we are just now hearing about it. It appears that the higher bromide when used with a oxidizer(ozone) will have a chlorine like effect, but not if we are doing up to a 35% wc/month, how much is dependent on how much of a water change and the build up of the bromine over time in our systems, now for a swimming pool the world health org, has stated that it is a possible carcinogen when used (the new stuff) in a swimming pool, and that it will affect the free chlorine levels. not good on either count.
I have asked the supplier for my pools to see if they can get a "non-DOW" supplier, they are looking into it.
what I was getting is also considered a "food Grade" what is the impact on us eating this stuff in our food!

Bromide levels in the thousands in a calcium chloride product will likely pose no health threat from a food perspective. The real issue, in our aquariums and in your swimming pool, is that brom ide quickly/easily converts over to brom ine (or brom ate) which is kind of bleach when it comes in contact with chlorine (in a pool) or ozone (in a reef tank). Bromate is more stable then chlorate (or chlorine) so will spend more time floating around in the aquarium looking for something to oxidize. Oh, and I really doubt the salt manufactures got caught with their pants down. Dow sent that letter out to their "bulk" customers last year. I'm sure the Marinelands/Oceanics/etc had time to find another supplier. Now, whether or not they decided to do anything about it is open to debate.

I'm glad to hear that our food should be safe, it does make me wonder if there has been any new testing on it, from a food safety aspect, IMO the more oxidizer's in my pool the better, (less bacteria) it's the "possible" carcinogen that bothers me there.
help me with this thought, we inject ozone for a quick oxidizer, would the "extra" that we get from a bromine just grab the next bacteria in line, we are not hurting for enough of them, in a reef tank, and possibly help the system? then end result would it not be a higher redox? (anybody wanna try?)
now that I think of it, there are some systems and some home pool oxidizer's that are bromine/bromate based. I remember that there were test kits for it. The problem may come around when you mix chlorine and bromate? if I remember correctly those were not supposed to be mixed.
I also think that the Oceanics,Marinelands, will be fine, I was referring to the smaller company's that bottle the calcium products.

Wow old thread.
That price seems reasonable, it is the shipping that will get you, 50 lbs to ship is never cheap. I bet you can still get peledow in Salt Lake at janitors supply or waxie I think they charge around $30 for a 50lb bag, or thats what they charged a few years ago.
For aquairum use you really don't want pleadow anymore since they changed it. I believe what you want to find is some of the Tetra branded calium chloride, they have a few different grades and the process they use does not have bromide in it.
here is their website
But I do not know where you can buy it around here

I use the Prestone Driveway Heat, I think it is called
Haven't noticed any ill effects from it
I picked up a couple of the "Homemade 2-Part" kits from Bulk Reef Supply and the "Calcium" bag looks like the exact same stuff...

I have really been wanting some of these calcium supplements and not sure where to get them either. So, snoyce, you say that pelowdow is not good anymore? Why is that?

I use Peladow and have not had any problems, but any Dow product after 2007 contains an elevated level of Bromide, many have used the new peladow, prestone driveway heat, without a problem but it is still basically uknown if elevated levels of bromide can cause problems and at what level you would start to have issues with it.
Randy on Reef central did post a chart that basically said if you do regular water changes it probably will not build up to a unsafe level if you use the new peladow to supplement calcium in a fairly low demand tank.
from what I have gathered on reefcentral all the major manufactures of aquarium products most likely switched to tetra products because there process contains no bromide, so if you can find some that tetra produced it is safer.
I have seen peladow and what bulk reef supply sells and some off brand icemelt that sams club sales cheap, and they all look the same to me visually so I don't think you can say what you have by looking at it
