Hi all, new to the forum here from SW pa. Just wanted to thank everyone for all the helpful posts on diy filters. Just got my sump filter and pvc overflow completed. Never would have happened if not for this site! I have 55 gal tank and just built a sump out of an older approx 15 gal tank. everything is going great so far. I plan on keeping some na natives including golden shiners creek chubs and blue gills. Thanks again!
