Saltwater storage

[MichaelP121579]

Last Saturday I bought a Brute Garbage can I washed it thoroughly and dried it. I mixed 30 gallons of water (rodi) Instant Ocean RC temp is 78.0 salinity is 1.025 a few mins ago I was getting ready for water change and I see this.
I kept the lid on it so nothing has fell in the water.
Any ideas?
Thanks in advance

How long has it been sitting? Looks like precipitate.

7 days today. I thought about running it trough a filter sock as I'm pumping to tank

Doubt that, most likely participate. I’m not a fan of mixing that far out. I only do it up to 24 hours.

Had RC salt do this to me on quite a few occasions. Did you dump all the salt in at once? I have the best luck adding the salt slowly so this doesn't happen.

+1 I generally mix and use mine within 12 hours.

I added 3 cups at a time until it got to correct salinity

Mixed SW does not store well long, better to have RO/DI on hand and mix when needed.
