I am talking about one of those breeder mops you use for tanks or ponds. A friend of my would like to know how to make or where to buy one? He live in AL. He said the looked on the e-net and didn't find anything. Can you guys help him?

I used these guidelines to make mine. I used bobbers instead of ping pong balls (just slightly cheaper). They did what they were supposed to, but the fish didn't cooperate.
