Thank you for the input. I noticed that there is still a significant amount of 3rd stage Hair algae in the back with the Water Sprite where I hadn't looked. The BGA hasn't expanded from it's original spots, though, and that's good. I did a 50% water change. I have to get an algae scraper. I've been using a razor blade and it's a little uncomfortable. That might help.
I figured out my dosing amount. I'm using an eyedropper. For my 10g at 20 drops per 1/4 teaspoon:
From the directions on the bottle: 1/2 teaspoon per 30 gallons, I come up with 3.33 drops rounded up to 4 drops. I'm going to have to check it over again.
Awsome feedback!! Thanks!
