    What is the green thing that sets infront of the cartridge? The cartridge is not in in this picture, because it is my hospital tank. But what purpose does the green thing serve? do i need to clean it all all? Do i meed to take it out during medication?

    The "green" thing is what your beneficial bacteria (BB) clings to enabling you to change cartridges and keep BB in the filter. Do not clean it. What are you medicating for?

    In that case you may want to clean it so that you do not contaminate the tank once the sickness is gone.

    Clean it now or after? the big tank has a seperate filter

    If it (the green thing) has been exposed to whatever sickness that the fish had I would clean it and place it back in after the signs are gone.. It would be a shame to kill the cotton mouth only to have it return.
