The intake of my fuval canisters has a plastic ball in it, i presume it is to stop large debris from going into the filter. My question is would the filters work better without them?
 
My Fluval 304 has a ball in the intake too, but it fell out when I was messing around with it. I'm not sure what the purpose of it is, but I didn't bother to put it back in. It's been floating around the top of my tank for a couple of months now with no ill effects.
