Getting ready to add boric acid to my dad's pool. Calculator says 28# will put it at 50 ppm.
Since I bought a 50# bag, I have a few choices-
1- Eye ball it, got with a bit more than half the bag and call it good.
2- Find a bathroom scale and measure it in a bucket or something.
3- Find a way to figure out the volume of 1# of boric acid.
I'd prefer 1 or 3, and my gut says 3 would be best, especially since I'll be adding a much lower amount to top of my pool. Anyone have any idea how to figure out the volume conversion? I have a DE scoop that I could use if I new the poundage/volume.
