There is a big problem, there is no easy way to empty a tank from a "wrong fluid" if they are not 1000mb. I use a lot of ender tanks to transport fluid output and input, but if by mistake, 1mb of the wrong fluid ends up in the system, there is no easy way to clean it up. If you break the tank, it will just revert to an "air frequency" tank.
The recipe to empty the content of a tank only works with the "air frequency."

Unless you make a "fluid filter" in the tank, so it can block other fluids from getting in, like the smart pipe.
Could you make it so that broken tanks keep their frequency so we can "reset it" in the crafting recipe?
