How much borax ...

[CaOCl2]

... do I need to add to a 30 000 liter pool to get a final concentration of 3% boric acid (w/w) ?

If I am doing my conversions correctly, that would be 3,000 ppm of borates. Why would you want to do that? You would be going well into the range where it is dangerous.

Thank you! It's purely theoretical though, and after posting my question I had an ah-ha! moment and all is well.
