Smell in stored saltwater

[mrbacony]

I mixed my first batch of saltwater a week and a half ago using HW Marinemix and a Brute trash can. I made my first water change the next day and then covered it for the last week and a half. I opened the trash can today and there is a bad smell coming from the can. Not overpowering, but a smell nonetheless. Should i be cracking the lid on the can? Or should i leave the powerhead on constantly? Is this normal?

Definitely have a power head going.if not anaerobic bacteria will start growing and slim will be on everything. I'd leave a way for oxygen to enter the trash can as well for good oxygen exchange and itll keep your ph up.

Is the water still safe to use, or should i dump and start again?

Its fine. Plenty of people dont waste the electricity and store it unmixed after the first day, myself included.
