Magnesium and Flakes

[Frop]

Basically I added a bunch of magnesium to this bucket (which should make it close to my tank's level). I mixed the water and heated it up last weekend. I never did a water change. So I set it aside and then this weekend opened the bucket to find it with a bunch of flakes. Is that from the magnesium? Is the water still fine to use?

Was it still mixing nonstop?? and or did you have a lid on the bucket? it could be a precipitate or if you had no lid some random debris

It only was mixing for a few hours then it was off for several days with the lid on.

I bet your calcium level was around 500 or higher when you added the magnesium

What exactly is in the bucket? Just the magnesium additive, or salt mix too?

Yeah it could be a precipitate too

Should be saltwater and the magnesium that was added a week before the photo.

Then it would probably be some calcium carbonate precipitate.

Then it would probably be some calcium carbonate precipitate.

Would something like that still be fine to mix into the tank?

Thanks for the reply

Yes. Salt mixes get calcium carbonate precipitates all the time.
