New saltwater Mix

[NDIrish]

I've used IO for years and have never had it mix up to anything but crystal clear in a couple hours. I don't heat mine, but I wonder if heating it, and having an air stone in it caused some sort of precipitate issues, or with the airstone it could just be microbubbles that make it look cloudy?

I'm thinking it maybe have been heating the water while mixing the salt.
I read that heating while mixing could possibly cause the calcium to precipitate.

Next time I'll mix it first then heat it to DT temperature.

IO recommends to put an air stone in the water to equalize the oxygen and carbon.

I use IO Reef crystals and always heated my water before mixing... I thought you had to... after a day I turned off the heater and just left the pump running to keep it moving. I started to notice by brute can was gross. I read on here and found the same thing, that heating causes it to percipitate... who knew? So now I don't even heat before adding to me DT. If I do a small water change it only drops the temp from 79 to 78. The rare occasion I do a large one then I will heat to 70 before adding. I heard 70 was the magic number to keep the temp at or under.
