One powder pack mixes with 50 to 100 gallons of water when using a fifty gallon barrel and a submersible water pump. When using the easy to use and operate in-line mixing device then mix one powder pack in five gallons of water. This five gallon bucket lasts more than 36 minutes before it needs to be filled with more water and another powder pack. The in-line mixing device works when you have sufficient water pressure pushing the water through the hose. It also requires that the water coming out has enough space to be released. This foam comes with no odor at all. As stated on the packets, it’s 100% organic. It stains as much as regular water stains. It’s as slippery as regular water is. It’s as harmful as regular water is.
