salinity is unlike any other salt currently produced and also has a tendency of behaving a little different. Any cloudiness will not be harmful if used but there are a few things that can help reduce clouding and deposits.
First, always mix at room temperature. The warmer the water, the more cloudiness is typically seen. Also, we have found that using a smaller pump really helps. I personally use a medium sized Koralia ( sorry, don't remember the model) to mix my 30 gallon vats at home and have no issues with cloudiness and residue. As strange as it sounds, it seems that the more agitation, the more cloudy the water gets. Lastly, we recommend using the salt within 24 hours, even if still cloudy. The cloudiness will clear fairly fast once added to the aquarium and will not harm any of the inhabitants. The longer any salt is mixed, the more time it has for the properties to degrade. CO2 dissolves into the solution from the surrounding atmosphere and will slowly break down components of the alkalinity. Using the mix within 24 hours helps reduce this effect.
I mix my 30 gallons in my garage and use the mix within an hour of two. Generally I have my RODI in the container a day or two before and don't start mixing until I am ready for my water change. I then add two big scoops of salinity and turn on the pump. Somewhere in the middle of cleaning up the tank I will check the salinity and make any adjustments which are typically very small. Then once I am finished in the tank I pump the water over and am done. My mix is almost always crystal clear and leaves very very little residue at the bottom of the drum.
I hope you find some of this info helpful, please let us know if we can help further.
. I will be getting a scale before I make my next batch.
