    Bromide and the DOW Bromide Scare

    Since Randy's return to the RC chem. forum I asked him to look at the Bromide issue via PM awhile back. He has now addressed the issue in full as best we can.

    Based on this calculation if you were using IO and need to boost up the Ca++ ~ 75 ppm or so the increase in Br - would only be about 2 ppm. Meaning it would be fine to still use it for as a boost even if you are using ozone.

    The second issue is the DIY or LFS two-parts. This still seems to be an issue and it is not advised at this time not use the DOW. As far a salt mixes, using the DOW, we do not know if they are going to fix it if they use the DOW but are assuming/hoping they will.

    As far as LFS two-parts, I know for fact, that TLF C-Balance has replaced theirs with Tetra and is more or less Bromide free.

    Yes it would, as Bromide and Chloride are both Halogen's and very similar in chemical properties and even ionic radius. Besides a dialysis membranes is much like a RO, so what good would that do as it would remove things like, Cl-, Ca++, Mg++, K+ etc. also. Or am I missing something on dialysis ??

    I said not at this time as a LFS or DIY or LFS two-part sup. However, we do not know when this DOW stuff will hit us, so a clarification is needed Many Ca++ suppliers still have the old stuff. The DOW can be determined, if it is safe if DOW bag lot number starts with U, which is 2006 DOW. So, it would "appear" that we are safe but I have no idea when the stuff will actually show up. You will need to look at the lot #. For LFS two-parts you would have to call the manufacture
