Oceanic salt giving calcium level of 650?

300F for an hour will convert Sodium Bicarbonate to Sodium Carbonate.
Or you could just buy Washing Soda.
The added Carbonate lowers Calcium levels by forcing it to precipitate. That's a dangerous practice IMO.
I would just let it fall naturally while maintaining normal Alkalinity.

What would the ramifications be of raising the alk in a bucket of make up water by this method? If the Ca precipitates out thats kinda the goal isn't it?

600g of baked-baking soda to 1 gal of ro/di
baked-baking soda... 1hr at 300*F as bang said
and yeah... you are doing this for your new water.. NOT in your tank.
if you have a high Ca load.. i would even adjust it at all

If the Ca is forced to precipitate out in the new water, is there any problem adding this water to the tank after the levels have been balanced in the new water?

in theory yes . . . in reality, no. Ca will precipitate out of solution at around 600 (no 100% sure on that number though)

calcium/magnesium precips when dkh is high and pH is high
precipitated ca is CaCO3... same thing as southdown sand and coral skeletons.. it is stable and realitively unreactive as long as pH is above 7 or so.
the caco3 will probably just stick to the walls of your waterchange bucket

Just one more small warning, when CaCO3 precipitates it also tends to lower Magnesium. I believe Oceanic might already be hign in Mg but it's worth mentioning.

Yep, this is an example of high alk, stripping calcium and magnesium right out of solution. Its like when they open the Ark of the Covenant and your face melts off

Seems to me we're seeing more and more negative post on this crappy salt mix everyday. I wonder if Oceanic was bougth out by Coralife:thinking:

Solonfairy quote:
the end result will be a solution that will raise dkh by 2 for every ml/g you add
example: in 20g of water... 20ml of finished solution will raise by 2dkh
Sorry, I don't get it. Is it 1 dkH for every ml/gal, or 2?

I do. My tank seems to. I have high Ca in my mix(680). I just keep alk normal. My tank does not consume much Ca, and I never have to add it.
I was using Oceanic, but it costs twice as much and other than an awkward package, salt dust that I can taste everytime I mix up a batch, I don't see any advantages. Ca measured high with that too. With Coralife, I get another useful bucket, and a T-shirt! Who could ask for anything more?
