Does water temp affect mixing salt?

So I plan on setting up a large salt mixing station. The only area I have enough room for this is in my garage. Problem is summer is coming, and the temperature in my garage gets up to 90+ degrees. What I have done in the past is put about 30 gallons or so in a brute can inside and run a fan and pump on it to get it down to about 78 and then mix the salt. Does anyone know if mixing the salt first and then cooling it down will cause any problems? TIA!

Mixing the salt into the water at a higher temperatures will help the salt dissolve faster and cooling it down won't have any impact

Well maybe it will work better then considering I have to cool the water regardless. Thanks!

Mixing in hot water will cause more precipitation to form on the pumps

Bad or expired salt have precipitation in any temperature.
Never had issues mixing good quality salt at higher temperatures.

Can you explain what I am doing wrong since I get precipitation of salt on my pumps when I mix at an elevated temperature and then cool it off?

Any new salt that has precipitation might be a bad batch so I suggest try a different brand.

Isn't it more likely that it isn't a bad batch and the issue is the heat causing the precipitation when it cools down? I am not going to change brands of salt based on a "might". Not when I have tested it, repeatedly, and its not the salt causing the precipitation, its the elevated mixing temperature.

If you have never had issues with precipitation based on elevated mixing temperature, how did you narrow the issue down to "Bad salt" for people who have had precipitation from elevated mixing temperatures?

Or, let me ask this. What would I need to do to convince you my issues isn't "Bad salt" and is indeed the elevated mixing heat?

Released dissolved carbon dioxide gas, causing the pH of water to increase, and that in turn can cause calcium carbonate precipitation.

Mineral deposits are formed by ionic reactions resulting in the formation of an insoluble precipitate. For example, when hard water is heated, Ca2+ ions react with bicarbonate (HCO3-) ions to form insoluble calcium carbonate (CaCO3), as shown in Equation 1.

In order to minimize the formation of insoluble carbonate salts when mixing, the following suggestions may be helpful:

1. Add the salt to a full batch of water, rather than adding water slowly to a large batch of salt. The latter allows a greater time at much higher than natural seawater salinity, which may tend to precipitate calcium and magnesium salts.

2. Stir the mixture vigorously as it is being dissolved.

3. If using a mix with a high initial pH, aerate the mixture as well as stirring it. The aeration will reduce the pH.

"As shown in Equation 1" from your first paragraph implies there is information missing. Can you post a link to where you copied that from? As it is, that doesn't include anything about the impact of temperature on mixing so I am interested in reading the rest of the article to see what, if anything, it says about temperature.

The higher temp should allow the salt to mix more quickly as warmer water has a higher capacity to hold dissolved minerals. I’d just double check the salinity of the water after it cools. Evaporation is the mechanism that allow the water to cool from 90 into the 70s, thereby altering the salinity as the water evaporated. I’d should be minimal but best to double check.
