No its not a pain, once I drain the water down I remove the lower, vented section which is where I have the sponge. Swish it in the used tank water & tap it against the side of the bucket of I see gunk coming out of it I'll remove it from the tube, dip it in the water & then squeeze it so more gunk comes out. Because its wet I have to use some to help stuff it back in usually. Putting the sponge inside also protects the fins from getting sucked into the tube.
