Yes, sponge filters do work better with lower flow rates, the same can be said for most media, but if you lack the space, then that might be an issue.

Different media allows for higher flow rates, sponge is relatively low and clogs pretty fast in most tanks.

I use them on filter intakes for canisters and on some overflows.
The media generally just needs relatively slow even flow, enough to maintain O2 levels.
