How do I properly cover my tank's filter with mesh to protect my fry??

Question

Two of my guppies are going to have their fry soon I think and I've heard it's a good idea to cover the filter with mesh. I have the kind that hangs on the side of the tank. Do I just cover up the entire filter with a piece of mesh? This is going to sound silly but could I use pantyhose or is that not hole-y enough and would this affect the filtration?

Answer 1

Try a piece of panty hose, I know it seems weird (if your a guy). Just use a rubber band around it and voila !
