The Eheim 2260 pumps 1900lph The 2217 pumps out 1000l/h nearly 2x its a monster. Works realy well i have had loads of filter and have just found Eheims the best, take them apart put them back, don't leak the only thing with the 2260 is its huge but as all my tanks are in a fish room not a problem. That bastard could be me
