So I'm mixing salt water to start to cure my rocks and I'm concerned how cloudy or dirty the water looks. The container is new, I washed it before using it with water. I used HW-Marine salt, and after 24 hours of mixing it looks dirty? Is this normal, does that go away, did I do something wrong? If it's normal how does it go away, obviously when I start to put water in my tank I dont want it to look like this. Picture attached so you can see. Thank you!!!

That doesn't look normal, what's the salinity? What's the make up fresh water? I'm not sure it will matter for curing Rock. I have the same brute trash can from home Depot (making a guess by the looks). I'd just follow normal curing procedure. Does it smell funny or anything?
 
Yeah it's the home Depot one. Everything looked normal until I added the salt. The salinity is 1.026. No smell.

What do you mean make of fresh water?
 
yeah, what's the fresh water, i.e. are you using RO/DI or just tap with chlorine removed? The HW-Marine salt "Optimized with amino acids and organically stabilized iodine". I don't have experience with that salt, but you might search for your salt and see who else has mixed it up. I just use Instant Ocean or Reef Crystals and no color. However over time it gets gunk in the mix (mold etc...) and I run it with Ozone for a bit and wipe the can down. It could be precipitate, do you see any white stuff at the bottom? How did you mix it? Vigorous mixing + air is my preference (old skimmer pump) + my transfer pump, but a good hand mixing plus pump is probably sufficient.
 
Can was totally clean, first time use, has the lid on. It's in my basement being mixed with a power head. It's tap water but filtered to remove chlorine plus a 0.5 micron filter. There's some salt laying on the bottom.
 
Is this the first time you've made salt with that fresh water? Probably just precipitation if there is still some salt at the bottom. Check the salinity and mix vigorously next time at the beginning, even with your hand to swirl it a ton. If the salinity is right it's probably fine, there just isn't that much to it, but leave the precipitate where it is. What hardness is your water? May just not dissolve fully if you have hard water. Any plans for an ro system?
 
I have very hard water, could that be it? I thought I shouldn't use the water softener, would that be better?

If I mix vigorously with my hand do you think that will help? Why does it matter to mix hard at the beginning? What exactly is precipitate?
 
I did a test (my first time) calcium 495, magnesium 1400. I'll have to get a hard water kit. Is this typical appearance of hard water?
