is a fluval 204 adequate for a 55 gal tank ? fresh water

If you plan to have a lite bioload (not too much fish and small in size), it should be enough. But it's always best to overfiltrate. Best to go with a 304/305 (rated for 70 gallon tank) or better yet, a 305/405 (rated for 100 gallon).

Bigger is better when it comes to filteration!
