I would either get a better power head/filter. The one I run is like that only it uses a water bottle and the powerhead that I have running is 100gph. Or I would cut the sponge in half. However if you go the sponge rought the bubbles might not disolve as good.
I might change my diffuser to look like yours, with mine I cant put a big enough sponge over the opening.... Ideas... Ideas...
