Let the tied bag with air in it float in the new tank water for 15-20 minutes to equalize temperature and slowly add tank water in 20 minute intervals to the bag. Don't pour the bag water in the tank, it will add any contaminates already in the bag, use a fish net to make the transfer.
it breaks stuf
It will contract and become smaller, because of the pressure of the water pushing down on it. It will get smaller and smaller the further under water it is.

First: Fill the 500 liter tank Second: Pour the water to the 300 liter tank, thus the 500 liter tank will now have 200 liters Third: Dispose of the water in the 300 liter tank Fourth: Pour the remaining content of the 500 liter tank(which is 200 liters) to the 300 liter tank Fifth: Fill the 500 liter tank(the 300 liter tank still has the 200 liters in it) Sixth: Pour the water from the 500 liter tank to the 300 liter tank(which already has 200 liters in it) Thus the remaining amount of water in the 500 liter tank is 400 liters

they will die
the glass tank explodes!xd
Just pour it into the coolant tank. Don't overfill, use 50% water and get an extra 15lb coolant tank cap.
