New Filter Considerations. Help needed!

[elliotulysses]

I believe someone suggested you stick a sponge on the end of your filter inlet if you are concerned about your frogs getting sucked up. That's what I would do.

all you need for a sponge filter is an aquarium safe sponge, and an air stone/pump. stick the stone into the sponge, and let the air run through the sponge. The air from the air pump will provide oxygen to the sponge, promoting beneficial bacteria growth on the sponge.

An ENTIRE sponge? How would one actually manage to properly block, unless they were saying to stick it in the take up hole?
Who did say that suggestion? I couldn't find it in my thread.

I can't remember, but it was on another thread. They sell sponges specifically for covering filter inlets, but they are expensive. You can cut holes in a regular sponge so long as the sponge does not have any chemicals on it. Sticking it in the intake might work as well, I've never tried it that way.
Pantyhose works as well, I've used those.
