( hence i use IO.. it's only 350 which was close to what i orginaly posted anyhow... i boost it w/ 2.5 tsp of dowflakes and its up to par... btw.. IO only cost mt $35 for 180 gal mix.. thats why i use it.. )

Sorry I wasnt referring to the post with the actuals I was talking about your previous post where you stated that in general salt mixes have a 360 ppm content. I should of clarified... But I dont agree with that, as I have tested my water with 3 different kits and have nothing lower than 400 at any given time and most of the time its at 450.
