[rossi]

How long can you have mixed salt water before you use it. Water is
heated and has a pump in the container the container is a brut new trash can
It has a top on it. thank you

It somewhat depends on the brand.

Regular instant ocean can be kept indefinitely. Some flavors have organics that degrade.

keep it as long as you need.......as long as it doesnt settle

I use Reef Crystals and I noticed that after a week or so, ALK Cal and Mag levels drop significantly compared to a mix that's been in a bucket for only a day. Now I only mix as much as I need a day or two before a water change. But if you have a FOWLR tank then it doesn't matter. I also hear that keeping the water heated for long periods of time will cause precipitation as well. But I haven't tested that out yet.

As long as you want...but I doubt this should be more than 3 months or your making too much. While I powerhead mine for movement and mix, I have never heater as It is not required. If you make only partial water changes, the temp does not drop enough unless you are changes for more than 20%.
Then again.....it does not hurt....so no problems
