Do you guys run all 8 bags?If taking out bags which ones and why?I know these guys that only use 2 bags 220 and 45 sometimes 220 and 73.Then at the end the water is poured through 25 bag.Wouldnt that make everything from 190 to 45 go into same bag.Seems crazy to me to only use 2 bags.I just wanted some other opinons because they swear by this method.
