i have a rena xp3 that i bought brand new a couple of months ago. i also have a eheim classic 2215 on the same tank but the eheim really kicks out the water whereas the rena has really slow output....,. the rena is supposed to be more powerfull than the eheim so if anyone else has one does theres kick out the clean water slowly or does it belt it out as i was expecting......?
got most of it with a water change and now the flow seems much better, but not as i would expect it to be!!!!!!!!!!
