It seems that for some reason or another sump and overflow filters dont seem to be that popular in freshwater applications. Seems like everyone suggests a canister filter. However, I was wondering if anyone has used or suggest a sump or overflow for freshwater and if so if they had any suggestions.

I've seen many people use an overflow/sump system for FW. Mostly, it's folks that have larger tanks, or that maybe bought a used tank that was reef ready (drilled with overflows). The benefits in FW would be the same as in SW IMO- added water volume, ability to conceal equipment like heaters, etc. Some people even put floating plants in the sump (with a light under the stand of course) to soak up nitrate/excess nutrients, kind of like a refugium in a SW tank.
