I am putting together my mixing station and have some great examples from this forum. I would prefer to use a Norweco or Ace Roto 55 gal vertical Cylinder tank but cannot find them locally to pick-up and refuse to pay 3X the cost of the tank for shipping. I have found, however the horizontal leg tanks (see pic). I've seen these used by several posters but have a question about dissolving the salt. The legs are hollow and the bottom of the tank have several crevices around the legs. For those who have used this tank - have you had problems with salt collecting in the legs? Have you had problems with getting the salt to evenly dissolve?
