Red Sea KH/Alk Supplement has chunks in it?

[Reefin' Alaska]

Just bought the Foundation B supplement and it came in the mail today. It has chunks in it?

Has it gone bad? Still okay to use?

Likely precipitation due to temperature fluctuations.

You can try to warm up the solution and shaking the bottle well to mix it back into solution.

Fill your sink with warm/hot water. Soak the container to warm the solution. Shake after you've warmed it. Repeat until the chunks are gone. You can still use the Red sea alk.
