I've had this sponge filter running in my established 29 gallon for about 6 weeks now. I'm just about ready to move it into a brand new 20 gallon. When I move it over, should I wring it out first? Or will the new tank benefit also from all the poop/etc that has built up inside the sponge? For what it's worth, I could also move my established heater to the new tank if you guys think the sponge filter is not enough.
