sodium carbonate not same as sodium percarbonate?

This company happens to have a location right near me. Here's their product list http://www.dumontchemicals.com/products.htm, I'm wondering what chemicals I could use in my reef tank that I can get bulk from them. One thing I could possibly use is the calcium chloride.

I have emailed them about magnesium chloride but haven't heard back yet.

What about sodium percarbonate? Not the same as sodium carbonate (washing soda)?

I could also use some of that and baking soda for my swimming pool!

No, not even

This chemical works similar to Sodium Perborate. The powders brake down into hydrogen peroxide when added to water and then to O2. They are a form of bleach that raises the O2 levels up very high.

Sodium Percarbonte = 2Na2CO3Ã"šÃ‚·3H2O2

Notice the 3H2O2, that is hydrogen peroxide. The reaction is;


2 Na2CO3 . 3 H2O2 → 2 Na2CO3 + 3 H2O2


then 2 Na2CO3 --- >4 Na+ + 2 CO3--

the H2O2 ---> H20 + O2


The pH of the solution is alkaline, which activates the H2O2 for bleaching. The powder contains about 30% H2O2.

This is the kind of stuff you find in non-chlorine bleach laundry soaps like Oxydol, OxiClean and things like Arm & Hammer toothpaste

Oops, sorry about the comma. Well hopefully they have magnesium chloride and calcium chloride at least.

Thanks for the excellent explanation of sodium percarbonate. Not something that I want to put in a reef tank...

Avoid percarbonates.
