Calcium Chloride Anhydrous Pellet

[Jason McK]

I'm currently using Calcium Chloride Anhydrous Pellet 94% to 97%
by DOW. I'm currently going through a massive die off of SPS and am scratching my head as to why.
I was using BRS Calcium Chloride but then found the exact same stuff locally so that is what I'm using. Any know of any issues with Calcium Chloride Anhydrous Pellet

Thanks
Jason

The Dow products are suppose to be ok. Have your raised your alk. significantly?

No ALK remains steady at 7-8DKH

Ya That's what I was thinking but most of the post talk about DOW Flake. I think I'll switch back

Both Dow's Dow Flake (dihydrate) and Peladow (anhydrous) Calcium Chloride are now high in bromide. You could look into finding some anyhydrous Calcium Chloride mfr'd by Tetra. Since they make their product from limestone, bromide shouldn't be an issue.

I really doubt that your calcium supplement is causing the die-off. I would find out what is in those 3-6% impurities.
