Small cell sponge for reactors?

[Enderg60]

I have a gfo reactor which comes with sponges, but it's a very large cell sponge and I'm getting GfO and ROX blowing by into the sump.

Can anyone point me to a small cell foam sheet that would work a bit better?

What reactor are you using?

I think I had cut up the large aqua clear sponge for mine.

It's an mrc reactor 4" diameter. Currently running at about 50 gpm.

I'm running into a similar issue with my Aquamaxx reactor. If I slow the input I don't get media movement, turn it up a bit and after some days I start seeing GFO in my sump. I could use some filter pad material but then I'll probably have to open the reactor every 2-4 days to swap it as it will just get dirty I'm afraid.
