i dont know why my post didnt appear, anyway. Brandy's on the parks Hwy carrier h202, and Alaska Jacks in Palmer also carriers it . H202 at the store is not the same thing. Hydro h202 is 29% and dose at 3ml per gallon . Peroxide from the store for 50 gallon of solution requires like 9 bottles ....not the same thing but could work in a pinch . Hope that helps.
