For a gallon of concentrate,, I use 5# dry FC and a gallon of distilled water ( slightly less concentrated). Add the powder to the water slow, outdoors. It will get hot, and give off chlorine.Wear safety gear....especially a face shield. For etching, I mix one part concentrate with three parts water. I store it in the etching tank.
