i was about to go run out and get some pantyhose for my filter intake(feeder guppy babies!), but thought I'd google it just to make sure it was safe. I ran across multiple threads saying they were safe, and others saying they weren't. Anyone actually use pantyhose to stop small fish from getting sucked into the filter, or have a better way that doesn't involve more than 5 bucks? Preferably not look bad as well, but I'm not picky.
