Well it's not huge and it never will be. Hopfully i will make a bigger one though. I don't have jars larger than 4 liters so thats the maximum size I can make it. 4 liters isn't that small though, its 2 bottles of soda. I have an xp2 which is about 6 liters but if you compair the media holding capacity, I think a 4 liter jar holds more. The 2 media baskets of an xp2 looks to be less volume than a 4 liter jar.
