What's the max salinity achievable?

What's the max salinity achievable with reef crystals salt and RODI water? Is it 1.030?

This buckets been running a week, still some salt left un dissolved.... it shows 1.030.

That's why I'm asking. Is this ok?

Depends on the temperature of the water, may I ask why you're going for such a high number or did you overshoot 1.025 and add too much salt? If that's the case you can add more RODI water to bring it down.

Also, any time I used RC salt it always had a bit of residue/calcium carbonate build up that showed up no matter how long I left it mixing. I just used all the water in the container but the last inch or so during a water change after getting the salinity to where it needed to be.

Oh just by error...i dilute to make it 1.025.

Calcium residue is ok...i thought it was un dissolved salt. Since i used a bag of rock hard reef crystals that hardened lol.

I've never had issues using hardened salt.

Thx

Yea I think it's just the residue in this case, I've heard some folks having a lot of it when they mix water, almost to the point where it looks like you put sand in the bottom of the container.

Be careful using bricked salt. I used some bricked up salt, and had issues. After some research I found that when the salt hardens, you get precipitate that doesn't go back into solution when you mix it. This is likely why you have some calcium precipitate in your bucket. I'd suggest testing the water before using the rest of the solidified salt to make sure you won't being lowering the parameters over time. I've also used hardened salt without issue, but it was a new bucket that got a little moisture in it and was just a bit clumpy, the problem showed up when I used a bag that had completely bricked up.
