hi i own a 422 tank. i not sure which pump to choose between eheim 1260 or eheim compact+ 2000 ? what i understand is that both are around 2000l/h but eheim compact+ 2000 consume less watt and cheaper but i worry the flowrate not reliable. eheim 1260 is long lasting but consume more watts and more expensive. i am more keen in eheim compact+ 2000 but i still got some doubt about the flowrate of compact+ 2000 and why is eheim 1260 cost more than the compact+ 2000 when compact+ 2000 got more advantage over eheim 1260, pls enlighten me or any advise ? thanks.
