I don't know about you guys,but I use Breeder's Nets alot. I've used them for the obvious-(babies),but I've also used them for fish that may have injured theirself,Grow-out Fish,Temp holding area's for Betta's,and even keeping Duckweed in the tank so my filter's wouldn't get clogged. What I found out was that when using these Breeder's Nets often,they tend to either rip at the top or just eventually fall apart pretty quick.You don't see replacement Nets,so I'd often find myself just buying a whole new Set-up.
A couple weeks ago I had some cory eggs and was searching frantically for a Breeder's Net,and when I finally found it,there were holes in it.Knowing that I had to get these eggs out of the tank quickly,I came up with Panty Hose!!!! Yep!!!
Just cut a piece off up around the thigh area-slide it up and around the Net box,and then tie a knot underneath the the box to secure.It stretches up around the fittings real easy and stays snug,and when you're done,you can rinse it well,or just pitch it out. It doesn't get any easier or cheaper than that. I have tons of Pantyhose that I've put a snag or two in-some I'm good for quite a while.
