I know amongst all the posts there are many about pickling, but I can't find one about how much Sodium Metabifulfite to add to how many gallons of fresh
water. I originally had a 110V
DIY Watermaker - useless and I see they are out of business. When I bought the system I got spares, including a
cleaning cartridge and a pickling cartridge. Problem is labels went black so no idea which is which as they look the same. I will be leaving
boat for awhile so need to pickle, thus I bought the Metabisulfite. I now have a Echoctec
pump and membrane.
