Easy mixing, ph right on no adjustments needed
great salt mix Mar 5, 2017
Used up my first box and just got my second. I raised my magnesium up to 1400 and this salt has held it steady. Calcium solid at 450 and alk at 11 steady. Mixes clean and clear. Stays stable when stored. Doesn't have any binders like other salt mixes so no gunk left in containers. Previous mix left bentonite clay build up and had to clean out barrel after every 50 gallon mixx. Only draw back is its a single bag for 200 gallon mix. Can't wait for the 50 gallon mix bags to come in. A great salt and highly recommend.
Easy Mixing, Great Parameters, Great Value Oct 4, 2016
An exceptional salt at a great value. I have been using this salt now for 6 months and am very pleased. It mixes easily without any clumping and it's parameters are spot on. My system was running on Hot Salt which at $90 for 200 gallons, I was very pleased to see RPM do so well!
