So I've once again depleted my 80 pound storage of morton white crystal solar salt. Had to get some more today due to some tail crunching from one of my males and it turns out all the damn stores stopped selling it for some reason. The only thing im left with is the morton system saver II formula pellets. Im not really wanting to try this since this thing says its got a ton of additives to do it's job better. Anyone else in canada know of or use other alternative salts like sifto or something?
