Does anyone use Eheim big (model 2222/2224)filters for their aquariums? I was given a 15 yr old slider and a 5 yr old stinkpot in November that live together in a huge 3'L x18"w x 17"h tank and this filter doesn't seem to put out much power, even though it's pretty big. I'm wondering where the best place is to find filter pads, media, and pump equipment since my dog chewed a tiny propellor piece this morning that I left on the floor while cleaning it out. Thanks, Mary
