I'm using a 200 micron mesh sock on my 75g tank. It looks just like Paul's last pic with the tape measure, except mine are 4 x 7 I think.
I change it out once a week and to clean I simply use a stream setting on my garden hose and squirt it inside to get all the gunk to the bottom. The I turn it inside out and repeat, but now all the gunk falls right out. A few more seconds of rinsing and its like brand new!
Total cleaning time for me is about 2 minutes max.
