I’ll keep this brief.

I want to add 50 ppm borates to my hot tub water.

Option 1: Borax + Muriatic Acid

option 2: Boric Acid

option 3: some sort of spa specific product

Can someone direct me to the best source for borates ? I’m looking for something I can buy/ship to Canada
 
Where can I buy Boric Acid ?

The link in my post is to a shop in Canada. Bioguard doesn't advertise "Optimizer Plus" openly as just boric acid (in the same way they don't advertise other products as baking soda). But according to the MSDS (second link in my post) it is 100% boric acid. In Australia, they advertise their "Optimiser" as 1000g/kg boric acid.

I know that this is probably overpriced, but if you don't find another source in Canada, it might be an option. I only found the 9kg bucket, which is probably a lifetime supply for a hot tub.

This might be the reason, why it seems to be difficult to find boric acid in Canada:
