Yep that is right.
10 ppm is a lot to get in a 5 ml dose. Notice it tells you that's over the solubility limit. In other words that much wont even dissolve in 500 ML of water.
Need to adjust the recipe for larger doses, like 20 ML instead of 5, etc.
Personally I'd dose 5 ppm twice a week instead of all at once, a 10 ML dose should work for that.
