LOL. No it won't explode. I don't have an Aqueon but I would imagine its the same as my Python. When I'm done emptying/vacuuming the tank I switch the valve shut or just pull it out of the water. You have to make sure the valve is shut before you refill the tank so you can adjust the temp of the water going back into the tank. It takes a couple times to get the hang of it but I'm pretty sure you're going to love it, I know I do!
