Boric Acid in Canada

[Easto]

Last year I used Borax + MA for borates.

I need to raise my borate level, does anyone know where to buy boric acid in Canada

Walmart used to stock borax - didn't see it the last time I looked.

Brentag Canada
Quadra Chemicals
Kemira Water Solutions

You may find that using BioGuard Optimizer in the 8 kg size comes out cheaper than the borax/acid combo, and it's much less of a hassle.
