Prefilter sponge or intake

[Suzanne B]

Greetings all. I wanted  to get opinions on which is better to prevent smaller fish from getting sucked into filter: prefilter sponge or stainless steel mesh cover over the intake.

I would think water would flow better with the mesh cover.

What are your thoughts?

I use a coarse filter sponge from a bubble filter from the co-op, while the mesh cover would allow more water flow, the coarse sponge will decrease the flow so they can't get sucked against the side like the mesh could. Plus it prevents fry from getting sucked in as well. Plus its an additional spot for beneficial bacteria to live, adding more biological filtration.

I lean towards a sponge for the above mentioned reasons. It's only drawback are looks and cleaning. Those stainless pipes look really cool and don't need much cleaning.

Thank you everyone for your input. I think I'll continue with the sponge. Just a concerned fish parent and don't want any of my little dudes to get hurt. I've got green neons and pygmy cories.
