Looking for a pre-filter sponge for AQ50

So today my snail was stuck on the intake portion on my AQ50 HOB filter. I'm getting some Crystal Red shrimp for my tank soon and at $10 a pop I do NOT want any of them getting sucked up lol. I'm looking at getting a pre-filter sponge for my AQ50.

I saw these.. not sure if they are for the filter intake or not...
I was also looking at these, not sure if they are big enough for my AQ50 intake though...
Finally found this, looks like really big pore's on the sponge for waterflow

Any suggestions on which one I should get?

I've thought about getting one of these myself.

Not sure but the Fluval and Hagen ones may be for specific filters/powerheads, though they could probably be made to fit.

The Filter-Max, from what I can tell is meant for more general installation - any filter with a round intake tube. Not sure if it comes with them (probably do), but adapters are available for different diameter tubes so it can fit various filters. There are also different sizes and sponge materials for different flowrates (Filter-Max I, II, and III)

Just read that the Filter-Max does come with three adapters.

Also, it looks like that vender That Pet Place only carries the Filter-Max III, which is for tanks over 40 gals.

Foster and Smith Aquatics carries all sizes. I've bought from both and have had good experiences each time.

I use a Fluval pre filter sponge on my AC50. I picked it up just to see if it would work and it does - other than needing a bit of thread tied around the top to make it snug enough to stay on. If there is a sponge that would stay on a little better that would be ideal, but this seems to work fine. Can't beat the convenience since I got it at Petsmart for a couple of bucks!
