I made my fist small batch of this salt yesterday and I have to say it is the cleanest mixing salt I have ever used.....It was mixed clear with in 10 min of everything being added, I didn't get a full test of the parameters but plan to on the next batch. I only mixed 5 gallons so it wasn't a major water change but the next one will be 10-20 gallons. So far it looks to be a great salt but witout test it is hard to say so I will get them on the next batch.
