Hi all, I'm looking for opinions or direct knowledge on how well an old-style Eheim 2213 cannister filter will work in a planted 20-gallon-high tank. The tank's doing very well with a present flow rate of 80 gph. The Eheim is rated at 116 gph. Would that extra 36 gph be too much added flow where the plants are concerned? TIA, Chuck Huffine Knoxville, Tennessee USA mailto:grendel at usit_net
