Do you have Early's Farm & Garden Centers in AB? They have used food grade 65 gallon drums that had food grade oils (flax or canola usually) in them for $20 each. You have to wash them out yourself which isn't easy, but the car wash helps! I have been using a couple for about 4 months now, and they seem ok. I have been testing the RO/DI water after it has sat in the barrels for several weeks and still get 0 tds. I'm hoping that means they are ok!!
