Hi, I want to find out if anyone is using the newer tunze osmolator with magnets for the sensors in the back chamber of a 24 gallon JBJ nano cube. I don't want to spend the money for this high end piece before I know it will fit into my system. Thanks for the input. Also where is the best place to buy one that will guarantee me the magnet holder instead of the long brackets. How are the reviews on the newer holders, do you guys like them or what have you heard? Thanks agian.
