I switched to the new Salinity from Aquavitro, and could not be more happier. Mixes almost instantly. Keeps my calcium at about 480, alk 8, and mag 1440. I never dose
+ 100000000000000000 On this one. I buy it by the barrel. A barrel is good for about 1,050 gallons. Costs about $300 or $400, but I have salt for the year. The important thing is to roll the barrel or bucket. Some additives may settle at the bottom, and you want even distribution of everything. Rolling the barrel mixes it all up very well...
I've only had foggy water once using Salinity, and that was my fault. I had the vent closed in the room where my mixing station is, and the water was not heated to the temperature of the house when it was mixed. But, I add the full load of salt to my mixing water when the mixing container is at the halfway mark with a powerhead on. I let the RODI continue to fill until it is full, then turn on my other mixing pump. I go to bed, then to work, and when I return home, it is mixed as well as it needs to be. The shortest mix I've done was 8 hours, but I generally do 24 hour mixes.
I checked parameters for the first 2 months of using Salinity, and it was so consistent and spot on, I don't really check the parameters anymore unless something has died in my tank, I do general maintenance and stir some stuff up, add a couple of fish, etc....
I have about 260-270 total gallons, so I do three 50g water changes per month. If I'm consistent with my water changes, my parameters show to be consistent as well...
