New to saltwater tanks. I purchased an established tank that a LFS maintained for a local church. Now it's mine and I transported 95% of the water and have everything set up. I went to the LFS to buy already made saltwater to fill the tank. However, I did not use all of it. I have 5 or so gallons left in a standard storage container with a lid.
My question is how long would this be considered "good" for? I am not sure if certain things from the container could ruin the saltwater over time or what.
