I have a 60g reef tank that has been up for about 1.5 years and has been doing great. However, I am concerned about the micron filter bag in my sump. It seems to be very full (looks like a balloon) and there seems to be water running over the outside of the bag vs through it. Other than less efficient filtration what are the implications--if any of this. Someone suggested cleaning it... I am hesitant to do that since I know alot of my biological filtration resides in that bag (right?). I heard of a few instances when people changed the bag or cleaned it their system crashed, is this possible? Recomendations or advice please.
