Some Dacron (white filter matt) on top to trap the gunk and stop it going through to the sponge. Then take the matt off each week and hose it off before putting it back on.

Ideal cheers

So other than that nothing more needed? Obviously normally you buy a filter rated to the tank so wondered if it was enough

It's a freshwater tank. You only need sponges to trap gunk and hold filter bacteria.
